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.
摘要翻译：提供了一种用于从用户的存储器提取信息的方法和装置，该信息将在以后的认证期间容易地被调用，但是攻击者很难猜测。这些信息可能是一个鲜为人知的事实，即个人与用户的相关性或公共活动周围的个人信息。用户被引导到适当的主题，并形成对用户而不是攻击者有用的间接提示。信息提取技术验证信息不容易被攻击，并估计问题和答案提供的保证数量。提取的信息可以是例如布尔（是/否），多项选择，数字，文本或前述的组合。注册过程可以安排向包含问题（但不是答案）的用户发送一个或多个提醒消息以加强用户的存储器。

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.
摘要翻译：提供了一种用于汇总文本消息（例如电子邮件消息或转录音频消息）的方法和装置。基于句子中的单词与一组单词的重叠程度，例如消息对象中的单词或者单词中的单词，提取每个文本消息（例如句子）的一部分作为文本消息的指示性摘要相关的根消息。提取的部分基于文本消息的每个部分的分数，诸如句子。还提供了一个接口，用于向用户呈现一组相关文本消息的指示性摘要。

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： 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.
摘要翻译：提供技术用于分析音频视频片段，通常来自多个来源。从文本相似性和视频相似性确定组合相似性度量。文本和视频相似性分别测量文本和视频的音视频场景之间的相似度。然后使用组合的相似性度量来确定音频 - 视频段中的相似场景。当音频 - 视频段来自多个音频 - 视频源时，类似的场景是音频 - 视频段中的常见场景。相似性可以转换为或通过距离测量。距离矩阵可以通过使用相似性矩阵来确定。文本和视频距离矩阵在确定组合相似矩阵之前被归一化。使用从组合相似矩阵确定的距离值来进行聚类。检查所得到的群集，并且当群集中的场景相似时，群集被认为表示两个或更多个不同音频 - 视频段之间的共同场景。

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.
摘要翻译：公开了一种查询定向密码方案，其采用具有通常不能使用在线搜索技术（例如用户意见，微不足道的事实或间接事实）与用户相关的答案的防攻击问题。在注册阶段，向用户呈现一个问题池，用户必须从中选择一个这样的问题的子集来回答。信息提取技术可选地确保所选问题和答案不能与用户相关联。可以选择将安全权重分配给每个选定的问题。选定的问题应该可选地满足主题分发的预定义标准。在验证阶段期间，用户受到用户以前回答的问题的随机子集的挑战，并且回答这些问题，直到超过给定应用程序的安全级别超过了正确问题的数量问题。可以通过将查询定向密码协议与一个或多个附加因素（例如来电者ID）相结合来进一步改善安全性，以确保可能仅向注册用户询问问题。
