It is described a method for certifying data containing a sequence of transactions comprising the following steps: finding a new transaction added to the sequence; computing a certification code for the new transaction taking into consideration all data preceding the transaction in the preserved order; saving the computed certification codes. In particular, each transaction will carry a certification code and a sequence number that uniquely identify all the data received up to the transaction. By saving the progressive transaction count and the relative certification code it become possible, at a later time, to verify the integrity of the whole data. The described certification method allows the use of electronic certification in the accounting world.
