806 results about "Personal identification number" patented technology

A personal identification number (PIN), or sometimes redundantly a PIN number, is a numeric or alpha-numeric password used in the process of authenticating a user accessing a system. The personal identification number has been the key to flourishing the exchange of private data between different data-processing centers in computer networks for financial institutions, governments, and enterprises. PINs may be used to authenticate banking systems with cardholders, governments with citizens, enterprises with employees, and computers with users, among other uses.

Method for generating customer one-time unique purchase order numbers

Multiple secure transactions are provided through use of a method that uses customer one-time unique purchase order numbers (“Coupons”) generated by an algorithm that uses a permutated user key and a user insertion key as input variables. A user key (such as a Personal Identification Number, or “PIN”) is combined with a permutation variable that is correlated with a customer sequence number to create the permutated user key. A random number generator is used to generate the user insertion key correlated with the customer sequence number. The algorithm can insert the permutated user key into a user account number through use of the user insertion key. A Coupon is validated by confirming that it is contained in a set of money source Coupons generated by a money source using the user key and a random number generator that is synchronized with the random number used to generate Coupons. Once a Coupon is validated, the matching money source Coupon and all earlier generated money source Coupons are deleted from the set, and a new set is generated. If a preselected number of Coupons are not validated for a chosen entity, an invalid user account number will be set. Coupons can be used for credit card or bank card transactions, and they can be generated without changing fixed digits of traditional twenty digit account numbers.

Method for generating customer secure card numbers

A method for providing secure transactions generates a Secure Card Number (“SCN”) for a first entity that is transferred with a first entity identifier to a second entity and then to a money source that verifies that the transaction is valid by use of the first entity identifier and the SCN. The SCN includes a 0Transaction Information Block (“TIB”), a Counter Block, and an encrypted Personal Identification Number (“PIN”) Block. The SCN is transferred to the money source in an account number or a non-account data field. The money source can use the TIB to determine whether the SCN should be used once or multiple times or to identify one of several physical devices, all of which are issued to the first entity, used to generate the SCN. The money source validates the SCN by duplicating the encryption process used to create an encrypted PIN Block and comparing the result to the encrypted PIN Block received with the transaction. A Triple Data Encryption Standard algorithm encrypts a PIN Block generated from a PIN, a Sequence Insertion Number (“SIN”) and a known starting value. The SIN can be a combination of three seed values and a random value generated by a Pseudo Random Number Generator (“PRNG”) initialized with the seed values. A Counter value is associated with the Counter Block and the seed values.

Method and arrangement for reliably identifying a user in a computer system

The invention relates to an arrangement and a method for reliably identifying a user in a computer system. The method utilizes a mobile station for communicating with the system. The method comprises generating a first one-time password in the mobile station by utilizing a known algorithm on the basis of the identification number of the user, subscriber-specific identifier, device-specific identifier of the mobile station, and time. The password obtained and the subscriber-specific identifier of the user are encoded and transmitted to an authentication server of the computer system, comprising identifying the user on the basis of the subscriber-specific identifier, searching a database for the personal identifier number of the user and the device-specific identifier of the mobile station associated with the user, generating a second password at the authentication server by utilizing the same predetermined algorithm on the basis of the personal identification number of the user, subscriber-specific identifier, device-specific identifier of the mobile station and time, comparing the first and the second passwords with each other at the authentication server, and if the passwords match, enabling the telecommunication connection between the mobile station and the computer system.

Self-authentication of value documents using digital signatures

An encryption-free technique for enabling the self-authentication of value documents (including personal and commercial checks) presented at a point of purchase or financial institution. Certain data contained on the value document may be signed with a first digital signature and authenticated with a public key certificate issued from a trusted certificate authority. The signed data and public key certificate are stored on the value document, preferably in a two-dimensional bar code data format. In the case of certain personal value documents (such as checks, credit cards, passports, birth certificates, Social Security cards, etc.), a unique personal identification number (PIN) also may be included in the document data that is signed by a second digital signature. At a point of purchase, a merchant or teller can scan and read the data stored in the two-dimensional bar code and other magnetically recorded information, and together with the PIN the customer provides, can authenticate the value document thus presented using the second digital signature. Alternatively, if the customer is not present, if the personal value document contains the second digital signature, the document may be verified using a PIN-generating algorithm or other method that generates all permutations of PINs. The first digital signature alone may be used to authenticate selected data within the personal value document even when the PIN is not available. Similarly, in the case of a commercial value documents, authentication of pre-printed data may be based entirely upon only the first digital signature.
