摘要:
The present invention relates to a method, system and computer program product for enabling the remote authentication of fingerprints over an insecure network using a client-server architecture by generation of a set of random queries relating to fingerprint patterns based on stored fingerprint data at the server, to which the client responds based on the observed fingerprint patterns, followed by the issuing of a randomly generates set of challenges pertaining to geometrical relationships between the fingerprint patterns for which confirm responses are received by their server, the final authentication being determined by the proportion of correct responses by the client to said challenges.

Methods and systems for providing user information from a wireless access terminal (W-AT) to a remote apparatus without revealing a primary identity of the user of the W-AT include generating an alternate user identifier for the W-AT, and providing the alternate user identifier and first information related to targeted-content-message information and/or user profile information to the remote apparatus.

A method is disclosed for encrypting a multimedia file including parsing the multimedia file to identify a media data portion; encrypting the media data portion; and, combining the encrypted media data portion with a non-encrypted non-media data portion. A method is also disclosed for playing a multimedia file including parsing the multimedia file to identify an unencrypted metadata portion; using the unencrypted metadata portion to locate a position of interest in the media file, the position of interest having an associated encrypted media data portion; and, decrypting the associated encrypted media data portion. An apparatus for performing the methods is also disclosed herein.

Methods and systems for determining a suitability for a mobile client to display information are disclosed. A particular exemplary method includes maintaining on the mobile client a list of first attributes relating to message cache misses of a cache memory located on the mobile client, receiving on the mobile client a set of target attributes associated with a target message, performing on the mobile client one or more matching operations between the first attributes and the target attributes to produce a matching result, and storing the target message in a cache in the mobile client dependant upon the matching result.
摘要:
Methods and systems for determining a suitability for a mobile client to display information are disclosed. For example, a method for determining a suitability for a mobile client to receive a targeted content message includes generating user profile data by the mobile client, receiving a set of target profile data associated with the targeted content message, the set of target profile data being descriptive of the targeted content message, comparing the user profile data with the target set of profile data to produce a set of confidence-level data, a target set of profile data describing the content of a respective targeted-content message, and storing the targeted content message in the mobile client based upon the set of confidence-level data.
摘要:
Methods and systems for receiving targeted content messages on a wireless access terminal (W-AT) are disclosed. For example, a particular method may include selecting at least one reception time based on a user profile and a targeted content message delivery schedule, and receiving a targeted content message at the selected reception time.
摘要:
Various systems and methods for of generating a user profile for use in providing targeted-content-messages to a wireless access terminal (W-AT) are disclosed. For example, a user profile with at least one profile element may be provided to the W-AT, and a profile confidence level for the profile element may be also provided.
摘要:
A targeted-content-message-related profile for use with wireless access terminals (W-ATs) may be generated by one or more usage-related rules on the W-AT itself. The usage generate rules may be used by the W-AT to generate a user profile, with the usage-related rule providing a dynamic property to the user profile. All or part of the user profile may then be used as a targeted-content-message-related profile for targeting content messages.
摘要:
Methods and systems for determining a suitability for a mobile client to display information are disclosed. A particular exemplary method includes generating a first value for a first targeted content message based on at least a first weighted sum of first user profile attributes, a user profile attribute being a numeric quantity relating to at least one of a preference and a demographic of a user of the mobile client, comparing the first value with a stored list of second values related to respective stored messages in a cache memory of the mobile client to produce a comparison result; and updating the cache memory based on the comparison result by storing the first targeted content message in the cache memory if the comparison result indicates a higher desirability of the first targeted content message over at least one stored message.
摘要:
A Digital Rights Management (DRM) system provides a lightweight layering of encryption and decryption of keys that allows efficient use of different cryptographic techniques to effect the secure delivery of multimedia content. Asymmetric cryptography, where a public key is used to encrypt information that can only be decrypted by a matched private key, is used by the DRM system to deliver symmetric keys securely.
