Definitions
- the present invention relates to systems in which part of the data records stored in the card is modified during a transaction carried out with a card reader and more particularly relates to a method for modifying the data of a memory card. during a transaction with a reader.
- Memory cards also called smart cards, are increasingly used as a data carrier associated with card holders.
- contactless cards for which information is exchanged by remote electromagnetic coupling between an antenna housed in the card and an associated reader have been developed as means of access to controlled access areas, means of identifying people or electronic purses.
- the memory containing the data in a smart card is generally a non-volatile, erasable and rewritable memory and preferably of the EEPROM type. This type of memory is divided into a plurality of locations containing data records of a determined length, for example 32 bytes.
- the memory and in particular when it is an EEPROM memory, requires a relatively long erase / write time (for example 5 ms), during which a possible power cut runs the risk of losing the data contained in the record.
- this method requires for each recording a backup operation in the buffer zone, an operation to erase the recording to be modified, a rewriting operation and an operation to erase the old recording in the buffer zone. , or 4 operations per record.
- the transaction includes many operations, for example 8 operations as may be the case, the transaction may take a long time incompatible with the time taken by the gesture of the card holder presenting it to the reader.
- this method has the major drawback that the records of the data zone are always in the same locations and that the buffer zone occupies a fixed place in the memory, this increases the "stress" of the memory and limits the number transactions that can be performed as long as the number of transactions for each location is limited to a given value guaranteed by the silicon manufacturer.
- the object of the invention is to carry out a method of modifying data of a memory card during a transaction which allows synchronization in all or nothing mode of the modifications to be carried out during of the transaction, this for a short period of time compatible with the access time limited to the card during the transaction, while avoiding the use of a part of the memory as a buffer memory for saving the data and therefore in avoiding memory “stress” due to writing data always in the same memory areas.
- the invention therefore relates to a method for modifying data in a card transaction system comprising a memory card and a reader capable of reading the card when the latter is in a determined position relative to the reader.
- the card comprises a first memory (RAM) and a second non-volatile, erasable and rewritable memory (EEPROM), the latter comprising locations occupied by data records in relation to the transactions carried out by the card, each transaction resulting in the modification of at least one of the data locations or the addition of a new record.
- RAM first memory
- EEPROM erasable and rewritable memory
- the method according to the invention comprises the following steps: a) for a data record to be modified or a record to be added, read from a previous control register located at a first determined location in the second memory the address of a free place in the second memory, b) write the new modified or added record in the free place, c) repeat steps a) and b) for each of the new records to be modified or added, d) write in a second place determined from the second memory a new control register containing the addresses of the free locations of the second memory to be used in the next transaction.
- the smart card used for the transaction comprises an EEPROM memory divided into identical sectors, for example of 32 bytes.
- An essential characteristic of the invention is the use of a control register occupying one of the sectors of the memory.
- This control register contains data intended to be used to carry out the transaction, including the identification of the free sectors of the memory that can be used to record there new data.
- the control register contains in particular the following fields:
- FlagOpen indicates whether a transaction is open or not
- PrevReg indicates the sector number where the previous control register was located.
- NextReg indicates the sector number where the following control register will be written, - FlagClose: indicates whether the transaction is closed or not,
- NewSect indicates the numbers of the free sectors for further modifications
- step 10 initializing 4 variables in the Card RAM memory:
- Control register address sector number in which the control register is located
- - NbUpdates variable incremented after each modification of a record or addition of a new record.
- TransactionLevel bit indicating that the transaction is in progress
- OldSector indicates the sector numbers where data is recorded during the transaction.
- the second step is the opening step of the transaction (step 12) during which the bit
- step 14 it is determined whether there is a record to modify or to add to a memory location (step 14). If this is the case, the old sector number is written in RAM memory (step 16), the address of the sector in which the new record must be written is read in the control register (step 17), the new record is written in a sector identified by a number read in the control register (step 18), and the modifications of the control data in RAM memory (step 20). The process then loops back to determine if there is still a record to modify or add (step 14). Note that the advantage of the invention lies mainly in the fact that a transaction almost always requires modifying several records, which allows the use of the control register without loss of time since the free sectors are indicated in the register without the need to search for them.
- a new control register containing new data is written in a free sector whose number is provided by the old control register (step 18), the old control register is erased (step 20), the old sectors containing records which have given rise to modification are erased (step 22) and the control variables of the RAM memory are reset to zero (step 24).
- the control register in sector 5 contains the following data:
- NewSect 7, 8, 9, 10, 11, 12, 13, 14 Assuming that the transaction is made up of four consecutive changes:
- the new control register contains the following data:
- the new control register contains the identification of the old sectors whose values were supplied by the RAM memory, the identification of the sector where the old control register was located, the identification of the sector in which the put the next control register, the numbers of the free sectors where the next modifications should be written, and the indication (FlagClose) that the transaction has been closed.
- the method according to the invention saves cycles if it is compared to the method calling for saving in a buffer memory.
- 4 EEPROM operations are required for each modification of data: writing to the buffer memory area, erasing the future location, writing new data to this location and erasing the location of the area. buffer. To this must be added the management of the buffer memory and the management of information relating to the data to be stored.
- the method according to the invention requires only 2 EEPROM operations for each modification, namely writing new data in a new sector and erasing the old sector, as well as 4 general operations, namely, writing FlagOpen to the control register at the start, erasing the old control register, writing the new control register and writing FlagClose to the control register.
