The present invention is a method for identification of manipulations on an arrangement which includes a sensor which emits pulses and a recording unit. As is the case with a tachograph, any possibility of manipulation must be overcome. For this purpose, the sensor transmits real time pulses to the recording unit and, cyclically in response to first request instructions, transmits higher data signals for a measurement, and receives a number of real time pulses in response to second request instr...

Disclosed is an optical disk barcode forming method wherein, as information to be barcoded, position information for piracy prevention, which is a form of ID, is coded as a barcode and is recorded by laser trimming on a reflective film in a PCA area of an optical disk. When playing back the thus manufactured optical disk on a reproduction apparatus, the barcode data can be played back using the same optical pickup.

An information reproducing apparatus includes an operation restriction section for stopping a normal reproducing operation by an information reproducing section for any information based on a signal other than another unique signal recorded in a recording medium loaded in a recording medium loading section if a predetermined period of time is elapsed after a judging section judges that the another unique signal read out by a information reproducing section or the another unique reproducing infor...

A digital subscriber communication terminal includes an adaptive output interface having a device key set, which, along with a subscriber device coupled to the adaptive output interface, determines a "shared secret." The adaptive output interface uses the "shared secret" to encrypt content and transmits the content to the subscriber device coupled to the adaptive output interface. The digital subscriber communications terminal includes a processor, a memory having an encrypted device key set and...

A method of detecting malicious binary executable files is accomplished by inputting a binary executable file; converting the binary executable file to byte hexadecimal text strings; calculating the frequency of each byte pattern in the byte hexadecimal text strings; selecting characteristic byte pattern frequencies as discriminating features; classifying the discriminating features as malicious or benign; labeling the binary executable file as malicious or benign; and outputting the labeled mal...

A method of scanning a computer file for virus infection attempts to identify whether the file contains program code and if it does, it then attempts to identify the compiler used to generate the code and performs a frequency distribution analysis of instructions found in the code to see whether it corresponds with an expected distribution for a program created with that compiler; if it does not, then the file is flagged as possibly having a viral infection.

A security intrusion mitigation system and method are presented. In one embodiment a security intrusion mitigation method includes utilizing network spanning tree configuration information to determine an action for mitigating diffusion of intrusive attacks. The spanning tree information can include an indication of an internal diffusion risks. An action for mitigating diffusion of intrusive attacks is automatically performed. The action for mitigating diffusion of the intrusive attacks includes...

An improved deep packet filter system designed to optimize search of dynamic patterns for a high speed network traffic. The improved deep packet filter system is a hardware-based system with optimized logic area. One optimization technique is the sharing of common sub-logic in the hardware design to reduce the number of gates that are required. Another optimization technique is the use of a built-in memory to store portions of the pattern set, also resulting in a reduction of gates. The reductio...

The present invention is directed to systems and methods for enhancing electronic communication security. An electronic communication is received and stored. A plurality of risk assessments are made with respect to the received communication thereby generating a risk profile associated with the communication. The assessments are made in a sequential manner by assigning the stored communication and index and serially placing the index on queue associated with interrogation engines that perform th...

The present invention is an information processing terminal capable of preventing leakage of identification information while adopting a general-purpose OS to provide development environment for a free application software and using a common keyboard for entry of identification number information and entry of other information. The information processing terminal is so constituted that a management mechanism comprises an execution management unit for operating a first and second information proc...
