摘要:
An IC card system includes an IC card (1), an IC card read/write unit (2) for reading/writing the IC card, a communication unit (10) intervening for connection to a communication line network (5), a controller (3) for controlling the IC card read/write unit and communication unit, and a server system (4) connected to the communication line network. The IC card (1) is written with at least specified access destination information for accessing the server system (4), the controller (3) automatically accesses the server system (4) through the communication unit (10) in accordance with the access destination information in the IC card, and the server system (4) offers information to an information offering destination (1, 3, 4) determined automatically by information to be offered which is processed by the server system (4), an information offering destination (1, 3, 4) already written in the IC card (1) inserted in the IC card read/write unit (2) or an information offering destination (1, 3, 4) designated by a user after the insertion of the IC card (1).

摘要:
Provided is a technology with which an electronic document including a plurality of elements such as texts and images may be partially encrypted and decrypted. An encryption-processing control unit receives a selection of electronic data included in an electronic document and a selection of an encryption key for encrypting the electronic data from among encryption keys stored in a storing unit. The encryption-processing control unit generates encrypted area data including partially encrypted data obtained by encrypting the selected electronic data with the selected encryption key, positional information for specifying a position of the selected electronic data in the electronic document, and decryption information including information that may specify a decryption key with which the partially encrypted data may be decrypted, and adds the encrypted area data to the electronic document.
摘要:
An IC card and a method thereof for adding or changing a program for a memory for writing without adversely affecting the function of the IC card and by keeping the security of a program to be written later by restricting writing by a write control program having a decryption function or a program code conversion function
摘要:
On the basis of information which is the standard for transaction conditions such as amount information in an IC card as well as age information registered in the IC card or a predetermined contract destination, a transaction when electronic money is used and restrictions and conditions for program audience are automatically set.

An electronic wallet system easy to use and having high security is provided. The electronic wallet system includes an IC card (2) for storing electronic money information, an IC card reader/writer (1) for reading data from, and writing data into, the IC card, an IC card loader unit (10) for loading the IC card into, and unloading the IC card from, the IC card loader unit, an IC card load controller unit (19) for controlling a load/unload operation of the IC card, and a lock signal generator unit (17) for generating an IC card lock signal in response to an activation of an unload operation by the IC card load controller unit. An electronic wallet system with an ID number specific to the system, applied to a POS system, includes a system ID verification unit (1010) and an input unit (1013) for inputting data to the system, wherein an IC card (1002) can be unloaded in response to an activation of an unload operation by a load controller unit (1018) and an input of the system ID from the input unit.
摘要:
A terminal 2 held by the user is provided with a radio transmitter and receiver 3. Electronic money information is transferred via the radio transmitter and receiver 3. By using a portable telephone, it is unnecessary to directly insert an IC card 1 into service supply equipment 17. In addition to the service supply equipment 17, a device 9 for storing electronic money information in a lump is provided. Since the electronic money information is transferred into the device 9 for storing the electronic money information in a lump, it is unnecessary to collect the electronic money information stored in terminals one by one.
摘要:
An encryption processing part of a controller of each of user devices specifies components of content as encryption target parts, creates an encryption key creation key by reading out a public key, for each of the encryption target parts, of a second user who is allowed to view the encryption target part, raising a secret key of an administrator of the content data to the power of the public key thus read out, and calculating a remainder, encrypts random numbers each corresponding to each of the encryption target parts by using the encryption key creation key, creates an encryption key for each of the encryption target parts, and encrypts, by using the encryption key created for each of the encryption target parts, each of the encryption target parts corresponding to the encryption key.
摘要:
To provide a novel authentication scheme to prevent PIN information from being exposed to the outside of a data carrier, without modifying an existing application for authentication management. The data carrier includes means for generating PIN information therein; a PIN storage unit for storing the generated PIN information with respect to the use of a service application; an authentication information storage unit for storing information unique to a user; an authentication application unit for authenticating the user by referring to the authentication information stored in the authentication information storage unit; means for verifying the PIN information stored in the PIN storage unit according to the authentication result by the authentication application; and a service application unit for performing a service according to the result of the verification of the PIN information by the verification means.
