  • Patent number: 7233671
    Abstract: A wireless device first successfully completes an Inter-RAT procedure, which is either an Inter-RAT handover, Inter-RAT cell reselection or Inter-RAT cell change order from UTRAN procedure. The wireless device then determines if a USIM is present. If the USIM is present, the wireless device determines if a new security key set was received and unused for ciphering and integrity functions during a current RRC connection. If a new key set was present and unused, the wireless device stores a value of zero into the USIM as a security START value for the CN domain associated with the RRC connection.

  • Patent number: 7171564
    Abstract: A method is provided for a user to generate a password for a software application accessible from a computer system which includes a universal password generator (UPG). The UPG includes a specified parameter for generating the password, and the software application requires the password includes a specified parameter. The UPG is initiated and the universal password is inputted into the UPG. The specified parameter required by the application, and the UPG specified parameter are inputted into the UPG. The universal password is processed such that the specified parameter of the UPG, and the specified parameter of the application are used to generate the password. The password is then transferred to the application requiring the password. The password may be saved and associated in the UPG with the program such that when the user re-enters the program, the UPG program retrieves the password for reuse in the program.

  • Patent number: 7152161
    Abstract: methods of embedding and detecting a watermark in an information signal (x(n), y?(n)) which are robust against sampling rate conversions of the watermarked signal (y(n)) adapts frame lengths used by an embedder and the detector, respectively, so as to preserve a constant ratio between the respective sampling rate and frame length. The frame lengths may be calculated from a greatest common divisor of a set of sampling rates providing watermarks which are robust against sampling rate conversions between any sampling rates of the set of sampling rates.
