Effective reduction of false alarms in large-scale video surveillance is rather challenging, especially for applications where abnormal events of interest rarely occur, such as abandoned object detection. We develop an approach to prioritize alerts by ranking them, and demonstrate its great effectiveness in reducing false positives while keeping good detection accuracy. Our approach benefits from a novel representation of abandoned object alerts by relative attributes, namely static ness, foreground ness and abandonment. The relative strengths of these attributes are quantified using a ranking function learnt on suitably designed low-level spatial and temporal features. These attributes of varying strengths are not only powerful in distinguishing abandoned objects from false alarms such as people and light artifacts, but also computationally efficient for large-scale deployment. With these features, we apply a linear ranking algorithm to sort alerts according to their relevance to the end-user. We test the effectiveness of our approach on both public data sets and large ones collected from the real world. © 2013 IEEE. Source

Nearly 13 million American adults who use social networks are more than willing to accept friend requests from strangers of the opposite gender, a new survey from Harris Interactive has found. According to Harris Interactive, 18 percent of men will accept a woman's friend request, even if they do not know the person. About 7 percent of women will accept an unknown man's friend request. A total of 5 percent of U.S. adults will accept every friend request they receive. Only 50 percent trust that their connections will keep their information private. Yet more than 24 million Americans leave their personal information "mostly public" on social networks. The results are based on a survey last month of 1,011 Americans 18 and over, including 387 who are on social networks. ID Analytics, a consumer risk-management firm, commissioned the survey, which was released today. Leaving personal information public and allowing practically anyone to view your profile is a dangerous prospect, Harris Interactive observed. The company said that the basic information found in a social profile can help "build the dossiers [that criminals] need to beat challenge questions and other security measures on financial accounts." It's a sentiment with which ID Analytics agrees. "Americans' lack of caution in friending members of the opposite sex online is striking," Thomas Oscherwitz, chief privacy officer at ID Analytics, said in a statement. "Friending someone online is not risk-free. Most social networking profiles contain personal information that can be used by fraudsters, and when you friend someone, you are giving them access to this information." One other interesting tidbit from the survey: respondents were twice as likely to say that having more business contacts than personal contacts in their list of friends is desirable.

Data brokers should give consumers more control over their personal information, and Congress should consider legislation that reins in the ways data brokers can use that information, the U.S. Federal Trade Commission is recommending. The data-broker industry "largely operates in the dark," with most U.S. consumers unaware that companies are collecting data about consumers' place of residence, interests, children, health conditions and income, said FTC Chairwoman Edith Ramirez. "Most consumers have never heard of the data-broker industry, let alone the names of the largest data brokers," she added during a news conference. "The industry suffers from a fundamental lack of transparency." Data brokers collect consumer data from "extensive" online and offline sources, largely without consumers' knowledge, with sources including consumer buying data, social-media activity, warranty registrations, magazine subscriptions and religious and political affiliations, according to a 110-page FTC report released Tuesday. The FTC has concerns about the "sheer breadth and complexity" of the data broker industry, Ramirez said. Data brokers store "billions[b] of data points about nearly every U.S. consumer," she added. In addition, many data brokers use "troubling classifications" based on race, health conditions and income to pigeonhole consumers, Ramirez said. A classification focused on a consumer's income could lead to limited offers for credit and other financial products, she said. A representative of the Direct Marketing Association, a trade group representing data brokers and other companies using data-collection services, didn't immediately respond to a request for a comment on the FTC study. In many cases, data brokers share information with each other, with consumer data often passing through "multiple layers" of data broker, the report said. Seven of nine data brokers studied by the FTC said they shared information with another broker, the FTC said. The FTC wants to "lift the veil of secrecy that clouds the data broker industry," Ramirez said. Congress should consider legislation requiring data brokers that provide marketing products to create centralized portals where data brokers share information about their practices and provide links to tools where consumers can access their information and opt out of data collection, the FTC report recommended. Legislation should require data brokers to give consumers access to their data and should require data brokers to disclose the names or categories of their data sources, the FTC said. Congress should also require retailers and other consumer-facing entities to receive consent from consumers before collecting sensitive personal information and sharing it with data brokers, the FTC recommended. For brokers providing people-search products, Congress should require data brokers to allow consumers to access their own information and opt out of having the information included in a people-search product, the FTC said. Those data brokers should also disclose the original sources of the information so consumers can correct it, and disclose any limitations of an opt-out feature, the agency recommended. The FTC report is a "powerful and disturbing privacy wake-up call," said Jeffrey Chester, executive director of the Center for Digital Democracy, a consumer privacy advocate. "The report reveals the largely invisible Big Data-driven complex that regularly spies on every American, comprehensively following our activities both online and off." Unlike a big data report, issued by the White House earlier this month, the FTC study "provides a much more realistic -- and chilling -- analysis of an out-of-control digital data collection industry," Chester said by email. But the FTC's calls for greater transparency and consumer control are insufficient, without additional legislation, he added. "The real problem is that data brokers -- including Google and Facebook -- have embraced a business model designed to collect and use everything about us and our friends -- 24/7," he said. The FTC voted in December 2012 to compel nine data brokers to disclose information that was included in the study. The nine data brokers in the study are Acxiom, CoreLogic, Datalogix, eBureau, ID Analytics, Intelius, PeekYou, Rapleaf and Recorded Future.

—A steady rain is lingering this morning from the monster storm that blew through San Diego over the weekend. Also lingering is what you might call my “curiosity of the week:” Don Casey resigned as CEO of the San Diego-based West Wireless Health Institute, just two years after he was lured from Johnson & Johnson’s Comprehensive Care group to lead the non-profit institute. Casey, who will retain his seat on the institute’s board, expects to accept a position with a major health care company, according to a statement. I wonder if the institute is still working to identify its role? I hope to get a chance to provide more insight about what’s happening there. —Timing is everything: The private online video sharing service that San Diego’s Givit unveiled in November officially started on Thursday—with an invitation to former FlipShare customers to move their videos over to Givit. FlipShare was the business that Cisco created from its $590 million purchase of Pure Digital Technologies, and then killed last year as the quality of video-enabled smartphones made a standalone camera increasingly irrelevant. Givit was created as a new business by San Diego-based VMIX. In an e-mail over the weekend, VMIX Founder and CEO Greg Kostello said user numbers are not yet available, “but the response has been really amazing.” —As part of its plan to acquire San Diego’s ID Analytics, Tempe, AZ-based LifeLock raised $100 million from venture investors and another $70 million in debt funding. LifeLock CEO Todd Davis said the database that ID Analytics created has been an important base for the identity theft protection services that LifeLock provides to more than 2 million subscribers. Financial terms of the deal were not disclosed, but I hope to talk soon with ID Analytics CEO Bruce Hansen. —Connect, the San Diego nonprofit established to support technology and entrepreneurship, has arranged an opportunity for half a dozen San Diego Internet startups to make presentations to … Next Page » Bruce V.
