摘要： Techniques are presented for analyzing audio-video segments, usually from multiple sources. A combined similarity measure is determined from text similarities and video similarities. The text and video similarities measure similarity between audio-video scenes for text and video, respectively. The combined similarity measure is then used to determine similar scenes in the audio-video segments. When the audio-video segments are from multiple audio-video sources, the similar scenes are common scenes in the audio-video segments. Similarities may be converted to or measured by distance. Distance matrices may be determined by using the similarity matrices. The text and video distance matrices are normalized before the combined similarity matrix is determined. Clustering is performed using distance values determined from the combined similarity matrix. Resulting clusters are examined and a cluster is considered to represent a common scene between two or more different audio-video segments when scenes in the cluster are similar.

摘要： A method and apparatus are provided for extracting information from a user's memory that will be easily recalled during future authentication yet is hard for an attacker to guess. The information might be a little-known fact of personal relevance to the user or the personal details surrounding a public event. The user is guided to appropriate topics and forms an indirect hint that is useful to the user yet not to an attacker. Information extraction techniques verify that the information is not easily attacked and to estimate how many bits of assurance the question and answer provide. The information extracted may be, e.g., Boolean (Yes/No), multiple choice, numeric, textual, or a combination of the foregoing. The enrollment process may schedule the sending of one or more reminder messages to the user containing the question (but not the answer) to reinforce the memory of the user.

摘要： A method and apparatus are provided for summarizing a text message, such as an email message or a transcribed audio message. A portion of each text message, such as a sentence, is extracted as an indicative summary of the text message based on a degree of overlap of words in the sentence with a set of words, such as words in the message subject or words in a related root message. The extracted portion is based on a score for each portion of the text message, such as a sentence. An interface is also provided for presenting the indicative summaries of a set of related text messages to a user.

摘要： A method and apparatus are provided for generating passwords that may be memorized by a user, yet not easily guessed by an attacker. A user is presented with one or more textual, audio or visual hints. A password is automatically generated based on the selected hint (and possibly further input from the user). The presented hints may include poems, songs, jokes, pictures or words. The generated password and selected hint can be presented to the user during enrollment for further reinforcement and stored in a user database for subsequent reinforcement and verification. The enrollment process may schedule the sending of one or more reminder messages to the user containing the hint to reinforce the password in the user's memory.

摘要： The disclosure relates to recognizing data such as items or entities in content. In some aspects, content may be received and feature information, such as face recognition data and voice recognition data may be generated. Scene segmentation may also be performed on the content, grouping the various shots of the video content into one or more shot collections, such as scenes. For example, a decision lattice representative of possible scene segmentations may be determined and the most probable path through the decision lattice may be selected as the scene segmentation. Upon generating the feature information and performing the scene segmentation, one or more items or entities that are present in the scene may be identified.

摘要： Methods, systems, computer readable media, and apparatuses are disclosed for providing event messages to a user. The event messages may include video data or a link to video of the event. In some variations, a user or content provider may define criteria for the event messages that are to be displayed to the user. The event messages may be stored so that a user may be able to browse through the stored event messages and decide when to view the video of the event. Upon a user's selection of the event message, the video of the event may be displayed to the user on the same display device or another display device.

摘要： A method and apparatus are disclosed that enable a user who forgets one of his two passwords to securely recover the forgotten password. After a user logs in using one of his two passwords, the illustrative embodiment reveals the other password to the user. The passwords are stored in a persistent table in both hashed and encrypted forms, but not in their original forms. The illustrative embodiment is advantageous over the prior art, where forgotten passwords are reset to a default value, in two ways. First, it avoids the inconvenience of a user having to log in using the default password, think up a new string that would make a good password, and change the password from the default to the new string. Second, it avoids the use of default-value passwords that might compromise security.

摘要： A query directed password scheme is disclosed that employs attack-resistant questions having answers that generally cannot be correlated with the user using online searching techniques, such as user opinions, trivial facts, or indirect facts. During an enrollment phase, the user is presented with a pool of questions from which the user must select a subset of such questions to answer. Information extraction techniques optionally ensure that the selected questions and answers cannot be correlated with the user. A security weight can optionally be assigned to each selected question. The selected questions should optionally meet predefined criteria for topic distribution. During a verification phase, the user is challenged with a random subset of the questions that the user has previously answered and answers these questions until a level of security for a given application is exceeded as measured by the number of correct questions out of the number of questions asked. Security may be further improved by combining the query directed password protocol with one or more additional factors such as Caller ID that assure that the questions are likely asked only to the registered user.
