Abstract
The method for forming a forgery-proof electronic signature is based on the fact that from data with a specific body feature of the signature-authorised person are combined with data which indicate the presence of the signature-authorised person. From this combination, one forms an electronic signature. Data, which indicate the precence are for example body-heat data or body sound. The forgery-proof electronic signature makes a secure data transfer possible.
Claims17
A method for forming a forgery-proof electronic signature, characterised in that from data (F) with a specific body feature of the signature-authorised person as well as data (W) which indicate the presence of the signature-authorised person, one forms a data combination (u), said data combination embodying the corresponding electronic signature.
A method according to one of the preceding claims, characterised in that the data (F) with the specific body feature are those of a fingerprint and that the data (W) for the presence of a signature-authorised person originate at least partly from the body heat of his fingerprint.
A method according to one of the preceding claims, characterised in that the data (W) for the presence of a signature-authorised person originate at least partly from the body sound of his finger.
A method according to one of the preceding claims, characterised in that the data (F) for the specific body feature and the data (W) for the presence of a signature-authorised person are sequentially read into a memory and this complete sequence is used as an electronic signature.
A device for setting up a forgery-proof electronic signature with the involvement of biometric data, characterised by a first means (F) which registers a body feature and prepares data from this and a second means (W) which registers the presence of a person from which one has recorded the body feature and a third means (CTR) which controls the output of information of the first two means, and a memory for recording and outputting the data from the information stored in a controlled manner.
A method for transferring data between a client (X) and a contractor (Y) with the help of a communication connection, characterised by the following steps:
- a) creating a first connection between the client and a central certification location (31)
- b) determining body-specific data (F) and data which characterise (W) the presence of the client (X),
- c) forming a data combination (u) as an electronic signature,
- d) transferring this data combination (u) to the central certification location via the first connection
- e) verifying the identity of the client by the central certification location by way of the data combination (u)
- f) creating a second connection between the central certification location (31) and the contractor (X)
- g) creating a third connection between the client and the contractor, and cancelling the first and second connection
- h) data exchange between the client and the contractor via the third connection.
