A system and method for the exchanging, distributing and managing digital content, along with providing users with the ability to sell and transfer digital rights of products or services purchased from other users, wherein the system and method are used to manage synchronization and the use of applications, web services and media in combination with different digital rights management (DRM) solutions to authenticate and authorize such transactions.

A method of providing varying levels of secure access to computer resources. A certificate is used to identify a particular data requester and the certificate is authenticated using asymmetrical encryption techniques, such as public-private key pairs. One or more trust authorities may be consulted to ascribe a trust level to the certificate, which is an indication of the veracity of the identity of the data requester. Individual system users may set differing levels of access to a number of shared system resources for a particular data requester. The authenticated and verified data requester is then provided with the pre-set level of access to the desired shared resource. The level of access to a particular shared system resource therefore depends upon the user the data is being accessed through, the authenticated identity of the data requester, and their ascribed trust level. The shared resource may comprise data and/or an application module that is accessed or executed through a secure symmetric encryption tunnel.

A content distribution is performed by a secure container including a content encrypted by a content key and container information set for a content transaction. The container information includes a person identification certificate identifiers list. Usage control status information including the list is generated and stored in a device during a secondary distribution among user devices after a primary distribution of the content. In the distribution among the user devices, identifying an identification certificate in reference to the list and performing a person authentication based on the identification certificate allows each of the user devices to use the transmitted content, when the authentication is affirmative.

A detection apparatus (102) connected to a device in a residence and an electricity meter (100) indicating an amount of electric power consumed by the device in the residence, the detection apparatus (102) including: a reception unit (1021) which receives the amount of electric power from the electricity meter (100); a collection unit (1024) which collects usage status of the device; a device information holding unit (1027) which holds device information including the usage status of the device and electric power consumption of the device corresponding to the usage status; and a determination unit (1025) which determines whether or not the electricity meter (100) is tampered, by comparing an estimated electric power consumption amount with the amount of electric power received by the reception unit (1021), the estimated electric power consumption amount being estimated from the usage status of the device by using the device information, in which the determination unit (1025) determines that the electricity meter (100) is tampered, when a difference between the estimated electric power consumption amount and the amount of electric power received by the reception unit (1021) is equal to or more than a predetermined threshold.

The present invention relates to multicast communication systems and in particular to the implementation of a random access uplink channel, which can be used, e.g., for transmission of acknowledgement messages for received data. In order to prevent frequent collisions on said channel, the transmission of acknowledgement messages is spread at least over time or, additionally, with regard to another distinguishing channel property, e.g. a RACH sub-channel or RACH-signature.

A line-of-sight-based authentication apparatus and method are provided. In the method, a first image is generated by photographing the eyes of a person using first lighting generated on the same axis as a photographing axis of a camera and a second image is generated by photographing the eyes of the person using second lighting generated on a different axis from the photographing axis. Eye movements are tracked based on the first image and the second image and a track of the eye movements is identified. Then, it is determined if the identified track is the same as a track previously stored for authentication purposes.

A credit card comprises a plastic layer, a processor, and a keypad. The keypad provides the ability to input a code (e.g., a personal identification number (PIN) code) to the processor as a part of validating the transaction. Illustratively, the entry of a valid PIN code may cause the processor to trigger an alerting device as an indicator to the merchant that the holder of the credit card is authorized for its use.

A portable telephone including a transmission and reception unit, a control unit, a speaker, a display unit, a code reader unit, an operation input section, a microphone and a storage unit. The storage unit includes a telephone number memory, a password-data memory, and a personal-attribute memory. A buyer scans a code, in which product information is encoded, using the code reader unit, and enters password data via the operation input section. The control unit performs a comparison of the entered password data and password data previously stored in the password-data memory. After the comparison, the transmission and reception unit transmits via an antenna the product information, the telephone number stored in the telephone number memory, and personal-attribute data stored in the personal-attribute memory to a mobile telephone company. The transmitted information is used in settlement of the sales amount.

The invention discloses a method and a system for enhancing the security of network transactions, belonging to the field of information security. The method comprises the following steps: a client sends a service request to a first server, the first server sends first information to a second server, the second server generates second information, and the second information is returned to the client by the first server so as to be supplied to a user; a security device receives the first information and the second information input by the user and generates third information for the user; the client receives the third information input by the user, the first server sends the third information to the second server, when the second server receives the third information, the second server generates an authentication code by utilizing the same method that the security device generates the third information, the second server compares the authentication code with the third information for authentication and returns results to the first server, and the first server executes transactions when the authentication is success and returns the transaction result to the client. The system comprises the client, the security device, the first server and the second server. The invention greatly enhances the security in the transaction process.
