In an information system, a web server records web access logs of a client outside of a LAN. A mail server records transmission/reception logs of e-mails. A DB server records access right operation logs. A task application server records DB access log. An administrative server collects logs recorded in the web server, the mail server, the DB server, and the task application server, and operation logs of the client terminals to trace a person and an operation related to information leakage using the collected logs.

A personal computer 50 holds encrypted contents data and a license acquired from a distribution server (10) over an Internet network (30) or from a music CD (60) using a CD-ROM drive. The personal computer (50), which is connected to a portable reproduction terminal (100) through a USB cable (70), performs a checkout operation for lending out, the encrypted contents data and the license to a memory card (110) attached to the portable reproduction terminal (100), and a checkin operation for returning the lent encrypted contents data and the lent license. As a result, it is possible to shift the encrypted contents data and the license acquired by software to the other device.

A computer program, method, and system for access control, which are capable of keeping and guaranteeing consistency of access control settings. A collector collects access control information and resource information which are set for each unit of processing such as an application and a file system and are transmitted from a transmitter, and stores them in an access control information memory. A combiner combines the collected access control information to create and store combined access control information in a combined access control information memory. A consistency adjuster analyzes the policies defined in the combined access control information stored in the combined access control information memory to detect inconsistency, and if inconsistency is detected, resolves the inconsistency according to an inconsistency measure policy. Thus, consistent filtering master information for the entire system is created and stored in a filtering master information memory.

A memory card (110) stores access restriction information (AC1) to a license information hold unit (1440) arranged in a TRM area. Access restriction information (AC1) has information for example of a frequency of reproduction allowed and a number of licenses owned. A controller (1420) in reproducing and transferring content initially confirms access restriction information (AC1) and thereafter effects reproduction and transfer and after the reproduction and transfer are effected updates access restriction information (AC1), as required, for storage in a license information hold unit (1440).

A storage medium on which is recorded a program for causing an information processing device. The program executes, an access right management information obtainment process for obtaining access right management information, a violation detection process for obtaining a policy from a policy storing unit for storing the policy set for the resource or the access to the resource, for checking whether or not the access right management information complies with the policy, and for detecting access right management information, a policy compliance level calculation process for calculating a risk score in accordance with a degree of risk of the violation, and for calculating a level of compliance with the policy.

A cellular phone has distributed encrypted content data and an encrypted content key stored in a memory. The encrypted content key data read out from the memory is decrypted by a decryption processing unit using key data Kp stored in a Kp hold unit, and then applied to a audio reproduction module. A decryption processing unit decrypts encrypted content data read out from the memory using a content key Kc extracted by the decryption processing unit to reproduce content data Dc.

A memory card 110 extracts a session key Ks from the data applied onto a data bus BS3 by carrying out a decryption process. An encryption processing unit 1406 encrypts a public encryption key KPcard(1) of memory card 110 based on session key Ks, and applies the encrypted key to a server via data bus BS3. A memory 1412 receives from a server data such as license key Kc, license ID data License-ID and user ID data User-ID encrypted with a public encryption key KPcard(1) differing for each memory card for storage, and receives encrypted content data [Dc]Kc encrypted with license key Kc from data bus BS3 for storage.

Data processing apparatus distributes a public key certificate and information about a private key to a user terminal as activation information separately from a terminal module. In the case where the public key certification is vulnerable, it transmits only the activation information again.
