A payment card number, primary account number (PAN), or simply a card number, is the card identifier found on payment cards, such as credit cards and debit cards, as well as stored-value cards, gift cards and other similar cards. In some situations the card number is referred to as a bank card number. The card number is primarily a card identifier and does not directly identify the bank account number/s to which the card is/are linked by the issuing entity. The card number prefix identifies the issuer of the card, and the digits that follow are used by the issuing entity to identify the cardholder as a customer and which is then associated by the issuing entity with the customer's designated bank accounts. In the case of stored-value type cards, the association with a particular customer is only made if the prepaid card is reloadable. Card numbers are allocated in accordance with ISO/IEC 7812. The card number is usually prominently embossed on the front of a payment card, and is encoded on the magnetic stripe and chip, but may be imprinted on the back of the card.
A sensitive data desensitization method for a banking service scenario
The application discloses a sensitive data desensitization method for a bank service scene, and belongs to the technical field of data desensitization, and comprises the following steps: obtaining a query result set, and traversing fields in the query result set; identifying whether the fields belong to sensitive fields based on semantic features of the fields, wherein the sensitive fields at least include one or more types of a name field, a mobile phone number field, an ID number field, a bank card number field and an account number field; selecting corresponding desensitization rules from a preconfigured desensitization rule set according to types of the identified sensitive fields; performing field-level desensitization processing on the query result set, replacing sensitive data field by field according to the selected desensitization rules, and generating a desensitized result set. By identifying dynamically changing query result fields, desensitization omission caused by non-uniform field naming is avoided, and by using a differentiated desensitization strategy, sensitive information is protected while data service availability is retained.

A bank card number generation method and device
Embodiments of the present application provide a bank card number generation method and device. The method comprises: determining whether first card number information with a self-selected tail number exists in the cache for the self-selected tail number of the bank card number; each card number information in the cache is loaded based on each card number information in the database; the database stores each card number information in a manner that each card number tail number corresponds to unique available card segment information; generating a bank card number based on the first card number information existing in the cache, and synchronously updating the first card number information in the cache and the database to second card number information; the second card number information has the same card number tail number and different card segment information as the first card number information, and the card segment information in the second card number information is in an available state. Without generating various bank card numbers in advance, the corresponding bank card number is generated quickly and in real time according to the current card selection demand of the user; the storage pressure of the database and the storage pressure of the cache are greatly reduced; and the speed of generating the bank card number is improved.
