  • Patent number: 8581694
    Abstract: An RFID tag interrogator is described. The interrogator comprises a time-out circuit and an actuatable RF signal generator for transmitting an electromagnetic signal. Upon first actuation, the RF signal generator transmits a first electromagnetic signal having a first limited total continuous transmit time that is no longer than a predetermined transmit-time. That transmission is followed by an interim period of a defined length where the time-out circuit renders the interrogator incapable of transmitting the electromagnetic signal. The interim period is followed by the RF signal generator transmitting a second electromagnetic signal having a second limited total continuous transmit time that is no longer than the predetermined transmit time. The time-out circuit prevents the first, second and subsequent transmissions of the electromagnetic signal that are each no longer than the predetermined transmit time after a prior electromagnetic signal has been transmitted until the interim period has expired.

  • Patent number: 8549307
    Abstract: Methods, systems, and apparatus are disclosed which enable flexible insertion of forensic watermarks into a digital content signal using a common customization function. The common customization function flexibly employs a range of different marking techniques that are applicable to a wide range of forensic marking schemes. These customization functions are also applicable to pre-processing and post-processing operations that may be necessary for enhancing the security and transparency of the embedded marks, as well as improving the computational efficiency of the marking process. The common customization function supports a well-defined set of operations specific to the task of forensic mark customization that can be carried out with a modest and preferably bounded effort on a wide range of devices. This is accomplished through the use of a generic transformation technique for use as a “customization” step for producing versions of content forensically marked with any of a multiplicity of mark messages.
