An electronic terminal performs early detection of unauthorized analysis thereon and prevents unauthorized acquisition and falsification of confidential information that is not to be released to a third party. The electronic terminal stores confidential information that is protected by consecutive application of a plurality of protection measures for defense against an attack from a third party. The electronic terminal monitors for attacks to the protection measures from an external source, and upon detecting an attack on one protection measure, updates a protection state of the confidential information to a new protection state in which either a new protection measure has been added to a protection path from the one attacked protection means to the confidential information, or the one protection measure on the path has been updated to a higher defense level.

摘要:
A management apparatus which collects, from a home appliance, home appliance information which is information related to the home appliance and provides a user with to-be-provided information which is information obtained from the collected home appliance information, includes: a managing unit which manages the home appliance information; and a home appliance information holding unit which holds, in association with each other, (i) the home appliance information and (ii) share information which is for sharing the home appliance information and is associated with the user. The managing unit refers to data held by the home appliance information holding unit when a request for to-be-provided information is issued by the user, obtains the home appliance information held in association with share information identical to the share information associated with the user, and provides the user with to-be-provided information obtained from the obtained information.
摘要:
It is an object of the present invention to provide an information processing device that verifies the authorization of an application that has issued an access request to access a device. For the present invention to fulfill the above object, when an application 102 on a universal OS issues a processing request to a secure device driver 105, a secure VMM 100 and an application identification unit 106 on a management dedicated OS 104 lock a page table of the application 102 and refer to the page table to generate a hash value. The application is determined to be authorized or unauthorized by comparing the generated hash value with a reference hash value.
摘要:
The present invention provides a migration apparatus that realizes safe migration of secret data between a first terminal device and a second terminal device. Before transmitting the secret data to the second terminal device, the migration apparatus (i) receives, from the first terminal device, a minimum evaluation level required of a destination of the secret data by the first terminal device, (ii) receives, from the second terminal device, an evaluation level of the second terminal device, (iii) judges whether the evaluation level of the second terminal device is lower than the minimum evaluation level, and (iv) sends the secret data to the second terminal device only if the evaluation level of the second terminal device is no lower than the minimum evaluation level.
