Time Stamp Patents (Class 713/178)
  • Patent number: 7634579
    Abstract: A method, system, and apparatus are provided for interpreting time data received from a server computer management device. According to the method, the local time at a remote computer may be received and converted to GMT. Once the local time has been converted to GMT, a command may be issued to the remote management device instructing the device to set its real time clock to GMT. The remote management device then maintains its time with reference to GMT. When data is received from the server management device, a determination is made as to whether the received data includes time data. If time data is identified, the time data is converted from GMT to a local time where the remote computer is located. The time data is then replaced with the converted time data in the received data. The received data, including the converted time, may then be displayed at the remote computer.

  • Patent number: 7631189
    Abstract: An apparatus for recording additional information hard to analyze in an information recording medium, a reproducer, a recording medium, a method, and a computer program for the same are provided. Bit values set at a plurality of DC control bit information setting positions set in a recording frame are decided based on constituent bit information of additional data, and additional data such as key information used for decoding contents is recorded in the information recording medium. In the reproducer, the additional data constituent bit information can be acquired by detecting the bit position set at a selected DC control bit storage position in the additional data-associated recording frame. With the configuration, it is possible to embed additional information such as key information used for decoding contents, key production information, contents reproduction control information, and copying control information with a format hard to analyze and also to accurately read out for data reproduction.

  • Publication number: 20090300364
    Abstract: An apparatus and a method for an authentication protocol. In one embodiment, a client requests for an authentication challenge from a server. The server generates the authentication challenge and sends it to the client. The authentication challenge includes the authentication context identifier, a random string, a timestamp, and a signature value. The client computes a salt value based on a username and the authentication context identifier from the authentication challenge. The signature value is computed based on the authentication context identifier, the random string, and the timestamp. The client computes a hashed password value based on the computed salt value, and a message authentication code based on the hashed password value and the random string. The client sends a response to the server. The response includes the username, the message authentication code, the random string, the timestamp, and the signature value.

    Abstract: A method for managing downloads of contents. This method provides for a replay memory that stores a globally unique right object identifier (GUID) and a right issuer timestamp (RITS). A duplication memory is used to store a right object (RO) in downloading a duplicate of content that is already stored in the replay memory. When a right issuer timestamp (RITS) included in the right object (RO) of the currently received content is less than the current time plus the set threshold value, and the globally unique right object identifier (GUID) and the right issuer timestamp (RITS) of the received right object (RO) are already stored in the replay memory, the received right object (RO) is separately stored in the duplication memory in association with the globally unique right object identifier (GUID).

  • Patent number: 7519666
    Abstract: A data transmission and reception system for exchanging data such as e-mail by using accurate time information over a network. An authorizing office authorizes an authorization mail server to issue electronic postmarks including highly accurate time information. Then, the authorization mail server stamps an electronic postmark with the highly accurate time information embedded in it on e-mail being sent by a sender. Here, the electronic postmark data, to which the time information has been attached in the authorization mail server, is made tamperproof by a predetermined electronic postmark issue program and further encrypted to be transferred to a receiver mail server.

  • Patent number: 7506162
    Abstract: In accordance with one embodiment of the present invention, there is provided a mechanism for implementing navigation seamlessly between sites in a computing environment in order to access resources without having to require users or user agents to re-authenticate. In one embodiment, there is provided the ability to determine different attribute sets for use with different resources on a target site for a user or user agent authenticated with a first site seeking to access one or more resources of the second site without re-authenticating. In one embodiment, there is provided the ability to map accounts on a first site to accounts on the second site using a set of attributes selected from among attributes provided by an application on the first site. With this mechanism, it is possible for applications or other resources to share information about a user or a user agent across disparate web sites seamlessly.

  • Publication number: 20090070589
    Abstract: A method and apparatus for authenticity and origin of Digital data such as recorded voice samples, video clips or still picture images etc. is provided. The method makes uses of the Trusted Computing principles to provide a secure, tamper detectable solution comprising of both software and hardware such that it can be verified without debate on its authenticity. The method comprises extracting reproduction avoidance key information and log information for captured data from stored information when verification of the captured data is requested, calculating reproduction avoidance key information using the extracted log information, comparing the extracted reproduction avoidance key information with the calculated reproduction avoidance key information and determining that the captured data has not been tampered, if the reproduction avoidance key informations are matched.

  • Patent number: 7490241
    Abstract: A method for time stamping a digital document is disclosed. The document originator creates a time stamp receipt using the document and the current time. The time stamp receipt is submitted to a time stamping authority having a trusted clock. The time stamping authority validates the time stamp receipt by comparing the time value specified in the time stamp receipt to the current time. If the time value specified in the time stamp receipt is within a predetermined time window, the time stamping authority cryptographically binds the time value and document, or the time value and some representation of the document, e.g., by signing the time stamp receipt with its private signature key.

  • Patent number: 7487359
    Abstract: A time stamping protocol has two stages referred to as the ticketing stage and the certification stage. During the ticketing stage, the document or other identifying data is sent to the TSA. The TSA generates a “ticket” based on the document or other identifying data and a time indication derived from a trusted clock. The ticket, which serves as an unsigned time stamp receipt, is transmitted back to the document originator. During the certification stage, the holder of the ticket requests a certified time stamp receipt by presenting the ticket to the TSA. The TSA verifies the ticket and generates a signed time stamp receipt, called the ticket stub, which is then transmitted back to the document originator. The ticket stub serves as a “universal time-stamp” that the holder of the ticket stub can use to prove the date of the document.
