摘要:
A way for securely protecting secret information—for example, a secret key—in a programmed electronic device is provided. A technique is disclosed for protecting secret information in a programmed electronic device that includes a non-trusted memory containing software, a data memory containing the secret information, and an access restriction logic unit that is adapted to allow or block access to the secret information wherein the secret information is adapted to be used for verifying the integrity of the software. In one embodiment, when starting up the programmed electronic device, the access restriction logic unit allows access to the secret information. Then the secret information is accessed for use in verifying the integrity of the software, and subsequently the access restriction logic unit blocks further access to the secret information. Embodiments of a semiconductor device and a programmed electronic device comprising similar features are also disclosed.

A system for, and method of automated data input that employs a mobile telephone as an input device. In one embodiment, the system includes: (1) a mobile telephone having a camera configured to generate an image of a document that contains the data, (2) a processing server adapted to receive the document via a wireless communication network, extract the data from the image and arrange the data according to a format and (3) a database, associated with the interpreter, that receives and stores the data according to the format.
摘要:
The present invention provides a method for authenticating a digital data unit of a mobile communications device. In one embodiment, the invention provides for the capture of a digital data unit with a mobile communications device and generating authentication data to confirm at least one of the source or integrity of the digital data unit.
摘要:
Apparatus and methods are presented for protecting data in microcontrollers from both malicious software processes running inside the device as well as from unauthorized attempts to read the data from an external data bus and/or external memory. An illustrative embodiment of the invention accomplishes these security improvements, in part, by utilizing an enhanced memory management unit (MMU). The enhanced MMU is configured to prevent one software process running on the microcontroller from accessing data associated with a different software process running on the same microcontroller. Moreover, data transmitted over an external data bus or stored in an external memory is encrypted, thereby reducing the chances that unauthorized users will gain exploitable information from this data.

The equipment is intended for exposing both side of printed circuit plates by means of a contact print. The equipment comprises a master copy and printed circuit plates holder in a rack provided with feeding elements and guided in parallel between two light sources and comprising respectively one portion above and below the exposure plane. The holder is formed of a dual frame (1) the two frame portions 2,2' of which are formed to be moved part and together relative to one another and in parallel to one another and while remaining in a position parallel with respect to one another. Located in the frame portions (2,2') of the dual frame (1) is respectively one transparency (4) framed by a frame (5) provided at least on one side thereof with alignment elements (15), with suction ports (7) being provided in its counterdirected surfaces (6) along the circumferential edges thereof. The said frames (5) are formed to precisely conform in size with respect to one another to be suitably placed into the frame portions (2,2').
