first_imgMasking of ultrasound cookies Explore further The permanent networking of mobile devices can endanger the privacy of users and lead to new forms of monitoring. New technologies such as Google Nearby and Silverpush use ultrasonic sounds to exchange information between devices via loudspeakers and microphones (also called “data over audio”). Citation: Ultrasound-firewall for mobile phones (2018, May 25) retrieved 18 July 2019 from https://phys.org/news/2018-05-ultrasound-firewall-mobile.html In the SoniControl project, Zeppelzauer and his colleagues Peter Kopciak, Kevin Pirner, Alexis Ringot and Florian Taurer have developed a procedure to expose the cookies and inform device users. For masking and blocking the ultrasonic data transfer, interference signals are transmitted via the loudspeaker of the mobile device. Thus, acoustic cookies can be neutralized before operating systems or mobile applications can access them. Users can selectively block cookies without affecting the functionality of the smartphone.The masking of the cookies occurs by means of ultrasound, which is inaudible to humans. “There is currently no technology on the market that can detect and block acoustic cookies. The application developed in this project represents the first approach that gives people control over this type of tracking,” said Zeppelzauer.All project results and the application have been made publicly available. The system is therefore directly usable and expandable for everyone. All project results have been released under Creative-Commons license.Data exchange via ultrasound in the Internet-of-ThingsThe technology is now being further developed in a follow-up project, SoniTalk. Through Internet-of-Things (IoT) technologies an increasing number of devices are communicating with one another. Ultrasonic communication is increasingly used for data exchange between mobile phones and devices. Thus, ultrasonic communication is an alternative technology for ad-hoc data exchange, near-field communication (NFC) and as a channel for two-factor authentication that proves the identity of users by combining two different and independent components.The new project SoniTalk wants to give users full control over what is allowed to be sent by which app and should effectively help to protect user privacy. The goal of SoniTalk is an open source, transparent and fully private-sphere oriented protocol for ultrasonic communication. SoniTalk seeks to lay the groundwork for a new free standard in the field of ultrasonic communication that enables secure communication and protects user privacy. Devices increasingly communicate via this inaudible communication channel. Ultrasonic communication allows devices to be paired and information to be exchanged. It also makes it possible to track users and their behaviour over a number of devices, much like cookies on the Web. Almost every device with a microphone and a loudspeaker can send and receive ultrasonic sounds. Users are usually unaware of this inaudible and hidden data transmission.The SoniControl project of St. Pölten University of Applied Sciences has developed a mobile application that detects acoustic cookies, brings them to the attention of users, and if desired, blocks the tracking. The app is thus, in a sense, the first available ultrasound firewall for smartphones and tablets. “The most challenging part of developing the app was to devise a method that can detect existing ultrasound-transmission techniques reliably and in real time,” said Matthias Zeppelzauer, head of the project and senior researcher in the Media Computing research group of the Institute of CreativeMedia/Technologies at St. Pölten UAS.Determining interests and locationSuch ultrasonic signals can be used for so-called “cross-device tracking.” This makes it possible to track the user’s behaviour across multiple devices, and relevant user profiles can be merged with one other. In this way, more accurate user profiles can be created for targeted advertising and filtering of internet content.Up until now, it has not been possible to block acoustic cookies. “In order to accept voice commands, the mobile phone microphone is often permanently active. Every mobile application that has access to the microphone as well as the operating system itself can at any time without notice activate the microphone of a mobile device, listen to it, detect acoustic cookies and synchronise it over the Internet,” said Zeppelzauer. Users are often not informed of this information transmission during operation. Only a permanent deactivation of the microphone would suffice, rendering the device unusable as a telephone.

first_imgA monstrously huge goldfish was recently captured in the Niagara River in New York. The goldfish was presumably a discarded house pet that may have been illegally released or survived a traumatic flush down a toilet. Buffalo Niagara Waterkeeper (BNW), a nonprofit working to protect and restore the Niagara River and Lake Erie watershed, caught and photographed the giant goldfish in the river’s Black Rock Canal, sharing an image in a Facebook post on June 14. [In Photos: Thousands of Goldfish Swarm in Colorado Lake] In the photo, Marcus Rosten, an employee of the nonprofit, cradles the fish in two hands; the orange leviathan measured a whopping 14 inches (36 centimeters) long, according to the post.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65770-giant-goldfish-in-river.html?jwsource=cl已复制直播00:0000:3500:35  An even more supersized goldfish was nabbed in California’s Lake Tahoe in 2013; it weighed in at just over 4 lbs. (2 kilograms) and measured nearly 2 feet (61 cm) long. Goldfish (Carassius auratus auratus) are native to eastern Asia and belong to the carp family. They usually reach about 1 to 2 inches (3 to 5 cm) in length when they live in aquariums or small fish tanks; at most, they grow to about 6 inches (15 cm) in captivity, according to the New York State Department of Environmental Conservation (DEC). But when goldfish are released into streams and rivers, they often grow to be 12 to 14 inches (31 to 36 cm) long. The first sightings of goldfish in New York waterways date to 1842; more than a dozen other states also noted the appearance of goldfish in rivers and streams by the end of the 19th century, according to the U.S. Geological Survey. Today, goldfish can be found in waterways across New York State, “the result of illegally released pets or escapees from bait buckets,” the DEC reported. The fish can survive year-round in the Lake Erie watershed, and goldfish reproduce very quickly; a handful of goldfish released into a Colorado lake in 2012 multiplied to number in the thousands just three years later. Invasive goldfish directly compete with native fish, and in large numbers, they upset the natural biodiversity of vulnerable freshwater environments, a BNW representative told Live Science in an email. “Aquatic invasive species that don’t naturally belong in the Great Lakes, like this goldfish, are a constant threat to the health of native wildlife populations and their habitats,” the representative said. Across all of the Great Lakes, goldfish populations are estimated to run into the tens of millions, the BNW posted on Facebook.

first_imgTelangana COMMENTS SHARE A day after Telangana Chief Minister K Chandrasekhar Rao dared the Opposition to face Assembly elections this year, several months before it is due in 2019, the Congress said it was ready for the challenge.In a quick reaction on Monday, the Telangana Pradesh Congress Committee (TPCC) President, Uttam Kumar Reddy, said KCR, as the Chief Minister and TRS supremo is known, should immediately resign. “Earlier, too, we had stated our readiness [for elections] and will humble the ruling party”.The Congress claimed it was well-prepared, that the TRS was in for a drubbing as KCR had failed on all fronts and that the people were disappointed with his tall promises. The AICC Secretary in-charge of the Telangana affairs, Ramachandra Kuntia said there would be no change in the party leadership, and that Uttam Kumar Reddy would lead the Congress in the upcoming elections.The TPCC had a detailed meeting to take stock of political developments. Among the attendees were Jana Reddy, Mallu Ravi, Bhatti Vikramarka, DK Aruna, V Hanumantha Rao, Sabitha Indra Reddy, et al. The party had recently organised a ‘Bus Yatra’ to to the districts to highlight what they termed the misrule and failures of the KCR government.On Sunday evening, KCR challenged the opposition comprising the Congress, BJP and TDP, to face snap polls, although elections are scheduled for April-May 2019, when the Lok Sabha polls are also due. The Chief Minister claimed he had discussed advancing the elections during his meeting with Prime Minister Narendra Modi in New Delhi, in early June.KCR had, while admitting senior Congress leader Danam Nagender and his followers into the TRS, made scathing remarks against the Opposition. The Chief Minister asserted that the TRS would win over 100 seats in the 110-member Assembly, quoting a couple of recent surveys.Nagender, who lost in 2014 on a Congress ticket, was earlier with the Telugu Desam Party. A leader of the Backward Classes, he has a strong following in Hyderabad, but was one of the leaders who opposed the Telangana statehood agitation. His entry will buttress the TRS in urban areas. In Hyderabad’s old city area, the TRS already has friendly relations with the strong MIM.At the event, KCR had exuded confidence that his government’s flagship Mission Kakatiya (irrigation) and Mission Bhagiratha (drinking water) schemes, and the progress of the mammoth Kaleshwaram (irrigation) project will bring about significant change to rural Telangana.Similarly, the Rythu Bandhu scheme, and the wide range of welfare measures will help achieve a Bangaru (golden) Telangana, he felt.

first_imgRELATED COMMENTS SHARE Stress is growingA major Himalayan quake is coming. But when? Arunachal Pradesh Published on SHARE SHARE EMAIL earthquake April 24, 2019 A medium-intensity earthquake shook Arunachal Pradesh early on Wednesday.There were no reports of any damage to property or casualties in the quake that occurred at 1:45 a.m.While the IMD said the quake measured about 5.9, the United States Geological Survey pegged it at 6.1.The epicentre of the quake was about 40 kilometres southeast of Along, and 180 kilometres southwest of the state capital Itanagar.State Director General of Police S V K Singh, who himself was awakened by the temblor, said he contacted the superintendents of police of all districts but no damage was reported from anywhere.The districts extend from areas bordering Bhutan, Tibet and Myanmar, he said.“Though people panicked there are no reports of any damage,” he said.Prof Trilochan Singh, who served as a geologist of Wadia Institute of Himalayan Geology for decades, described it as “shallow earthquake”, considered dangerous for its impact within a radius of 40-50 km.Mild earthquakes often occur in this Himalayan state, located in seismic zone 5, Singh said.The earthquake zoning map of India divides the country into 4 seismic zones (Zone 2, 3, 4 and 5) unlike its previous version, which consisted of five or six zones.According to the present zoning map, Zone 5 expects the highest level of seismicity whereas Zone 2 is associated with its lowest level.A strong 6.3-magnitude earthquake also struck Tibet close to India early Wednesday, authorities said.There were no immediate reports of casualties.The quake, which struck at 4:15 a.m., jolted Medog county in Nyingchi city which is located close to Arunachal Pradesh.

first_imgPublished on A day after the Lok Sabha election results were declared, showing a massive saffron surge in West Bengal, the power equilibrium is already seen to be shifting distinctly towards the BJP in the State. Even as celebrations continued in the BJP camp, rumblings could be heard within the Trinamool Congress (TMC). Party supremo and Chief Minister Mamata Banerjee said she will take stock of the performance.An unprecedented Modi wave saw the BJP win 18 seats in the State, registering its best ever performance. The BJP wrested seven of the eight north Bengal seats and 11 more in south Bengal. The TMC saw its seat tally come down to 22 in 2019, from 34 in 2014.Post results, Mamata has maintained a low profile. She skipped her customary press conference and reportedly refused to meet senior leaders of her party. A tweet congratulating the winners and calling for a review of her party’s performance came barely five hours after the counting began. On Friday, she put out a poem title I do not agree.Rumblings within TMCAccording to party sources, a review meeting will take place on Saturday and all 22 winning MPs, the 20-odd losing candidates, grassroot-level leaders and other senior functionaries across different wings of the party have been invited. “Polarisation on religious lines have happened and money power was used to sway voters. The Modi wave and an organisational shortfall within the TMC are also factors (leading to the loss),” observed Firhad Hakim, Bengal’s Urban Development Minister. But the rumblings within the party are much stronger. A senior party functionary said he had raised objections to the “language” that was being used by the top leadership and other issues — like division of voters on religious lines — being taken too lightly. “The review meeting will see heads roll, and some being sidelined,” the leader pointed out.Mukul Roy at work?In what appears to be punitive action, the TMC suspended Subhranshu Roy, son on BJP leader Mukul Roy, for six years. While the party spokesperson cited “anti-party comments” as a reason, others claimed that it was Subhranshu’s failure to contain the BJP’s surge in parts of Barackpore. Barackpore became a prestige issue for Mamata after dissident leader Arjun Singh switched over to the BJP and won the seat, defeating Dinesh Trivedi. Mukul, a one time confidant of Mamata, was the architect of the switch.“I am proud of my father. He has single-handedly destroyed the party (TMC) that he once nurtured. But my party (TMC) perhaps does not trust me. But I will talk to my father,” Subhranshu said, hinting that he is open to all options. Meanwhile, the BJP stepped up its attack on the TMC. Party leaders claimed that “many disgruntled” TMC leaders are willing to switch over. In fact, Prime Minister Narendra Modi, at an election rally here, had maintained that at least 40 TMC MLAs were in touch with him.The State BJP leadership is looking to up the ante on local issues like the alleged involvement of the ruling party leaders in ponzi scheme scams and “syndicates” (a loosely used term to denote extortion rackets). The BJP will organise a victory rally in Bengal that may be attended by party President Amit Shah. COMMENT May 24, 2019 Elections 2019 West Bengal SHARE SHARE EMAIL SHARE COMMENTSlast_img read more
