Abstract

A digital declaration is provided by an individual on a terminal (1, 22) in order to strengthen the binding force of a digital declaration of the agreement with a document. The digital declaration includes at least one item of characteristic information of the document and an item of digital recording information, which comprises at least one excerpt of a recording of an action, statement or capacity of the individual, said recording being generated by a recording device (7, 10, 12) essentially at the time of the declaration of the agreement. The item of recording information is associated with the information of the document by the terminal (1, 22) in order to provide the digital declaration. In order to increase the security of the agreement declaration provided by the digital declaration, the digital declaration and/or the digital item of recording information and/or the document are/is preferably provided with a digital signature. Since the individual is conscious that he, or an action, a statement or act by him, is recorded when submitting a declaration and is retained in the digital declaration, the submission of the declaration becomes a conscious act of will. The binding force of the agreement with the document is strengthened and it can be shown, in particular, that it was issued by this individual.

Description

Digital declaration method for generating a digital declaration and software product for carrying out this method

The invention relates to a digital declaration according to the preamble of claim 1, a method for generating a digital declaration according to the preamble of claim 5 and to a software product for performing this method according to the preamble of claim. 9

Networks to transmit information, such as the Internet, are for the communication of increasing importance. They simplify communication and business activities. In order to use the new possibilities for handling business jobs as safely as possible, methods for the electronic signing of documents have been developed. The spectrum of these methods extends from the onset of scanned signatures to digital signatures use public key cryptography. Subdocument digital information is to be understood that information in a corresponding context has a meaning. Accordingly, a document includes a character string (text document), or a digital recording, for example, a sound or an image, especially an image of a paper document.

For a digital signature include at least a secret key. Because the digital signature is assigned to a person, even the secret key of a person must be assigned. To ensure that only the right person can create a digital signature with the secret key, they must ensure that the secret key can not be used by another person. To ensure the legal validity of digital signatures, policies and laws for the digital signature to be worked out in many countries and also by supra-national organizations. In the EU-signature law different terms are retained. A digital signature within the meaning of the law is generated with a private signature key seal to digital data that can by means of a corresponding public key, which may be provided with a signature key certificate of a certification authority, identify the owner of the signature key and the integrity of the data , A certificate authority is a natural or legal person who certifies the assignment of public signature keys to natural persons. A certificate is a provided with a digital signature, digital certificate of the assignment of a public signature key to a natural person or a separate digital certificate, which contains further information in clear reference to a signature key certificate, such as an expiration date expires to which the certificate is. The certification body and the person who owns a private key, must take steps to ensure the secrecy of the private signature key, a storage of private signature key is not permitted in the Zertifϊzierungsstelle. A CA can confirm with a time stamp in the form of a digital signature that their specific digital data were given at a particular time. From US 5 136647 a solution is known, according to which any digital documents, such as text, video, audio or image data can be provided with a time stamp.

In networks with multiple CAs, the authenticity of the assignment of a public signature keys can be assigned to individuals across multiple CAs. can then be trusted development agency of the signature key certificate of a certain certification when the trustworthiness of this certification authority is confirmed through a chain of certification authorities. This chain must be different from the party that received the digital signature to the certificate authority that created the signaled turschlüssel certificate extend. From US 6 134550 a solution is known with which the chains may be established via CAs with the smallest possible effort. The US 4 868877 describes another solution to increase the authenticity of a digital signature, the underwriting authority of the person signing is defined more closely by other criteria, such as budget or required joint signatures.

Technical components with safeguards are required for the production and storage of signature keys and the generation and verification of digital signatures, reli- forged digital signatures and manipulated signed data sig recognizable. The generation of a digital signature must be indicated and it must be noted the data to which the digital signature applies. From WO00 / 73879 a computer system with a specially secured representation processor is known. The presentation processor ensures that a displayed document is provided without modification with a digital signature, the private key is read from a smart card and triggered the signing process through a secure switch. To generate, in addition to a time stamp digital signature with increased safety, the US 5422 953 describes a solution in which a clock on the smart card is used in conjunction with the clock of the computer system.

The US 5 606609 assumes that in a large proportion of business transactions, no expensive digital signatures are needed, but that should be used for these transactions user friendly safety technologies. A solution is described by a collection module for collecting security information. The collection module collects the user's desired safety and brings them into a predetermined format. carried out the drawing of the document by the user by the security information associated with the document. The security information can be extracted from the document, at least to verify a security aspect of the document. The security kön- nen include, for example document summaries and gescante signatures.

Both in the use of digital signatures as well as in the use of less secure safety information, such as scanned signatures, the recipient of an order drawn statement should be confident that the holder of the signature or security information for the declaration will stand. But a digital signature and a signature copy is not a personal signature as an original signature by hand. The main difference is in the actual portability of digital signatures. All that it takes to generate a digital signature, the private key. The owner will keep this acting in his own interest secret. Can the private keys are used by a third party without authorization by the key holder but, as the recipient of the signature does not look at this. If the signature of a person is demonstrably used without their consent for contractual statements, that person may not be required by the statements may. At most, she meets and the true signer liability and the contract has not been concluded.

In the known safety and especially with regard to digital signatures is a systematic abuse risk because a digital document, particularly a private key is enough to create a signature that is indistinguishable from one generated by the authorized person signature. Who will receive a signed and a recognized private key contract, thus has no means a certainty on liability. In the Swiss signature bill, the liability of the signature holder equals designed as an output, if it's private key should not have well protected. Similarly, a burden of proof be provided that: The signature owner would have to prove, in dispute that the signature was created without his will. but it is unclear how such evidence can be provided and how this regulation fits into the existing contract law. To think is also not just cases of stolen private key, but also to manipulation through viruses and software errors. In addition, false programs that lend themselves instead of a desired program due to confounding appearance in terms of a Trojan horse could lead to unwanted signing of transactions. Viruses, Sofwarefehler and unwanted programs can cause the customer believes to sign a statement A, while a declaration is signed B in the computer, in fact and truth. Since the signing is a highly technical process, the user must be confident that everything is going right in his computer. So it is indeed easier thanks to recognition of digital signatures in a dispute the origin or authenticated assignment to prove a connected with the declaration signature. but it opens up loopholes that can make the legal certainty gained nothing.

A further disadvantage of digital signatures and can be used as security information in a document signature copies is that this pressure by a KEYER can be connected to a document. The more often the sign is triggered by pressing a button, the unconscious of the individual signing process is experienced. Also questions as to whether an in-processing signing process should be completed with the belonging to the listed information document that awareness of the process can not really raise. A keystroke leaves a significantly lower debt compared to the signing by hand. Correspondingly weaker and the awareness of the signed document and its contents will be. Now, if the person who triggered the digital signing with one touch, is confronted at a later date with the consequences of signing, it may be that it lacks the memory of the agreement with the document. Particularly if it has, for example, its time to stop a first signing process because of doubts and because of a subsequent pulse is mitlerweilen forget the signing has yet been carried out. The assumption of the computer have triggered something you did not want to then emerge, and it will be the liability of the only apparently signed documents be doubted. This gives rise to disagreements between the connected through the document seemingly each other parties. In addition, the quality of the programs used to sign is called into question.

The invention is due to the shortcomings of the solutions according to the prior art, the object of the invention to find a solution, with which the consent may be given to a document by a person digitally so that the liability of the digital agreement is increased with the document and is especially shown that it was given by that person.

This object is solved by the features of claim 1 and 5, and. 9 The dependent claims describe alternative or preferred embodiments.

In the solution of the problem was recognized that the authenticity of the assignment of a pub- lic signature key to an individual is not the authenticity of which could increase the liability of a digital signature. This is because the digital signature is given by the private key and this key is not bound to the person to whom it belongs. The private key can not have on its digital information beyond authenticity. To submit to a terminal or computer, a digital agreement with a document with increased liability, the consent must be so tied to the person that direct authenticity of the person flows in delivering the Einverständisses the agreement. So there must be similar as with an original signature on paper, are held something that can not be provided by third parties and which the accordance from an obligation to the person to be a liability. According to the present invention is made substantially at the time of declaration and delivery connected as a digital recording information with the document a photograph of an action statement or property of the person. When recording an acoustic or sound recording and / or an image or video recording of the person and / or a write action of a person can be used. A write action is detected for example by a touch screen pad in digital form. Because the person is aware that they, or an action, statement or action by it, is taken in making a statement that the declaration to a conscious act of will is. If it tion is in the explanation to the signing of a document, so the signing because of the increased awareness will adhere better forget literally. The signing is no longer just a keystroke, but an act of will that is recorded, remains in memory and is authentic, such as a handshake or a signature.

Because the voice and image of a person is not falsifiable, could only be tried for a possible abuse to assign an existing recording a new Unterzei- chung. but this is not possible if it is ensured that, when signing a recording must be made and that only those directly associated with the document image will be affected. Thus, the control over the assignment of the document or connection with the consumption is the person who explains the agreement, this connection is carried out by the terminal with the person.

In order to increase the relationship of the discharged recording consent opposite, it is expedient if the signed from the receiving a reference to the agreement, or kument to Do, is apparent. In an acoustic recording could

speaking person as to which document they signed. It goes without saying that the concluded fiscal various information can be spoken to business corresponding respectively. Here, the text to be spoken, for example, from the terminal or computer can be preset by about a superscript text DAR on the screen must be read aloud. Even if only a picture of the consent-giving person is taken, so this leads to greater liability than a copied signature or a standard image that is only used. This is especially true when from raising awareness to the recording, for example, by looking in the camera or a homemade sign or a gesture seen. The enhanced binding is due to the authenticity of the recording at the time of delivery of the agreement. In order to increase the relationship of the captured image for each business, even a facial expression, a posture or a gesture could be chosen, which makes the picture stand-alone, or is in a relationship with the business. If necessary, the recorded shall in the picture peculiarity examples game, a hand signal, given from the computer and copied by the person. It goes without saying that the image section can also be selected so that together with the person also information about the business, such as a section of the screen is held in the picture. In a video recording a variety of images and also preferably also a sound track is recorded. thus it is a recording that can combine all the above-described possibilities of sound and image recording.

For the recording, a microphone and / or a picture or video camera and / or a touch screen pad is needed that which or which is so connected to the computer, or the terminal apparatus to the network, or that the digital information the receptacle can be attached to the document. It goes without saying that other images can be used when these photos capture an action or property of the person so that they can be clearly assigned to the person. The digital statement of agreement or the signature thus comprises at least an indication to the document and a digital recording. The digital recording together with an indication to the document forms a digital declaration. Because the authenticity of the person and, where appropriate, an indication of the made declaration or the signed document from the record is clear and / or because the person from which the shot is taken, assumes that from the made in connection with the document recording seen a liability, a liability is achieved, as occurs for example in a signature by hand. The risk that the signing will be forgotten, is reduced significantly.

A digital declaration may be used alone or preferably combined with a known digital agreement declarations or with the digital signature. Starting from a solution according to the US 5606 609 digital declaration would be taken as an inventive security information from the collection module in a predetermined format. In dispensing of acceptance of the document by the user, the digital declaration and optionally further security information with the document would be connected. With the digital declaration, the authenticity of the signer in connection with the document could be verified. Starting from a solution according to the WO00 / 73879, the computer system would additionally be connected to a recording device comprising a microphone and / or a camera, especially a video camera and / or a touch screen pad. The digital recording information generated by use of the recording apparatus could be provided with the illustrated and signed document with a digital signature, so that the digital declaration would be protected against changes. In addition to digital and digital terschrift UN Declaration, a time stamp may be used. At a time stamp according to US 5422953, a clock is used on a smart card along with the clock of the computer system. A time stamp according to the US 5 136647 is introduced from a time-Certification in a digital document and secured with a digital signature. It goes without saying that only the digital declaration can be provided with a time stamp.

At high demands on the integrity of the digital declaration, or their digital recording, a solution can be applied, as described in US 5499 294th In such a solution the digital processor a Aufnahmevor- direction, such as a camera, a sound recording device, or a touch screen pad, a private key is assigned. In addition, the camera or recording device also has a public key. The processor of the receiving device can determine from the digital receiving a hash value, encrypt it with the private key and so generate a digital signature. The digital recording and the digital signature can now be compiled along with a document information to a digital declaration with corruption fuse. To check that the digital recording is unchanged, the digital signature is verified using the public key and determines the real hash value of the digital recording information. If the hash value of the stored digital recording coincides with the real hash value of the digital recording, the stored image has not been altered.

It would also be possible to record the installation of a signature with a picture or a video camera. Here, the signature could be mounted on a printout of the document to be signed. If the signature is provided on a screen pad, so the recorded signature can only be used as a digital recording for creating a digital declaration. Preferably is displayed on the touch screen pad at least one characteristic part of the document, and optionally a date, so that the appropriate signature is introduced together with the illustrated when signing on the Screen pad information in the digital declaration. In a high security needs of both the recorded signature and the image or video recording, which documents the signing can be introduced in the declaration. If only the recorded signature is used particularly shown on the screen pad document information, so, it is important to be able to prove that the signature was recorded as a consent form with a defined document and not simply copied. For this purpose, the digital processor of the screen pad can be associated with a private key, the encrypted determined from the recorded signature and the document information shown in recording a hash value and this comparable with the private key of the processor. The digital declaration with the secured screen pad receiving the signature shows that effectively a signature is written to the document, and that is not an existing record of the signature was only used. Because the person has signed on the screen pad, a similar liability is incurred, as in signing a paper document. If for signing the Do- kumentes together with the digital declaration with the recorded the document signature and a digital signature is required, this substantially corresponds to the signing of a paper document and the simultaneous presentation of ID, the private key to the digital signature, the function of a has ID. to securely hold the belonging to sign holding the date and in the digital waste of acceptance of a document would, preferably, a time stamp is used. Optionally, however, the date is recorded on the screen pad and held together with the signature in the digital recording, which is used to create the digital declaration.

The invention is further described in the figures by way of examples. Here, FIG. 1 shows a perspective view of a computer with various devices connected thereto,

Fig. 2 is a schematic representation of a computer with various devices connected thereto, and Fig. 3 a perspective view of a mobile phone (cell phone) that is used for example, as access to the Internet

Fig. 1 and 2 show a computer 1 having a screen 2, a keyboard 3 and a mouse 4. The computer 1 is connected to a local network 5 and via the local network 5 to the Internet. 6 It goes without saying that the connection can be made directly to the Internet. 6 The computer 1 a receiving device is at least connected, take an action, or an action, a statement or a current property, in particular the appearance of a person and can lead to an input of the computer 1 to-. When the recording apparatus feeds the recording in analog form to the computer, an analog input, the computer is used via which the inclusion of a digitizer can be fed. In a receiving device, the output of which provides a digital signal, the recording may be directly supplied in digital form to the computer. In the illustrated embodiment three different recording devices are presented. An image or video camera 7 allows image or video recordings, especially a computer one person using to supply the computer first The digital image or video signal is made available as an image or video connector card 8 to a PCI bus 9 (Peripheral Component Interconnect). A microphone 10 is connected to an input / output device 11, or to an analog input of the input / output device. 11 With the microphone sound recordings can with statements a computer person using added and the PCI bus 9 are made available, wherein the input / output device 11 or associated apparatus makes the sound recording digitizable. Possible additional cradle a screen pad 12 is shown. The screen pad 12 can be used to draw up a writing action of a person are used. The overwrite recording is supplied in digital form via the input / output means 11 to the PCI bus. 9

As a further device connected to the computer device 1, a card reader 13 is illustrated. With the card reader 13 information may, for example, a private key, are read from a smart card 13a. The card reader 13 and the keyboard 3 and the mouse 4 are connected via the input / output device 11 on the PCI bus. 9 The signals and records generated by the devices connected to the computer equipment 1 can use the PCI bus 9 and a bridge 14 made accessible to the central processor 15 °. The processor 15 is connected to a RAM memory 16 and optionally connected to a ROM memory 17th As other components of the computer 1, a hard disk 18 and, optionally, a CD-ROM drive 19 are connected via a data interface 20 with the PCI bus 9 or connected to the central processor 15. For access to an external network, possibly via a local area network 5, a network interface 21 is provided. This connection to an external network, preferably to the Internet 6 enables a person using the computer 1 to make contact with another network user or a service. in the computer 1, then, if a document is to be transmitted with the approval from the person to the computer 1 the other network users or the service, then the document creates a digital declaration and transmitted to the other network users or services to the person who discharges the agreement. The digital declaration includes a characteristic information about the document and a recording of an action, statement or property of the person who gives to the other network users or service their agreement with the document. The liability of the digital agreement will be increased by the digital declaration.

When receiving an action may sound recordings of the microphone 10 and / or image or video images of the camera 7 and / or write record of the screen pads 12, which are made substantially at the time of declaration of consent to the document, be used. From taking an action must make a statement, or at least indicate the current presence of the person who agrees with the document. When using a sound recording, the person may speak a text which is displayed on the screen about the second In the spoken text, a statement is made preferably has a reference to the document. Preferably, the current date and a characteristic feature of the document is mentioned. If this is the document is an order, the quantity, the product and the date is about mentioned. If this is the document is a unilateral declaration, in particular a liability to a second opposite, or an indication of an official body to act, the essential point of the statement is as noted on the record.

In a video recording, an image sequence can, together with a sound recording, as has already been described recorded and associated with the document. If necessary, a pure image or video recording is also used only without sound. It can contain information about the document the reference to the document on gestures and / or image areas are made. Image areas, which are based on the document can be generated by the person held by paper, or by the recorded next to the person Bildschim. 2 but the liability can be increased already by an image, particularly a portrait of the person concerned when the image was recorded at the time of the declaration of acceptance of the document. This is especially true if these image-recording the person is conscious. The image has because of the hairstyle and the clothes of the person something specific.

When the overwrite recording or writing image of a screen pads 12 is used and is coated with this is that it has been recorded at the time of declaration of consent to the document, there arises a liability, such as those in a real signature on paper given is. It goes without saying that the binding is increased by combinations of the described record. For example, the signing can be held on the screen pad 12 by the camera. 7

The observation made by a recording apparatus recording, or an extract thereof, is provided as digital recording of information in the computer 1 and is connected to at least one characteristic information of the document, wherein the compound of the recording information is performed with the information of the document from the computer. 1 The digital declaration thus generated is produced at the terminal of the person who explained to her by mutual understanding with the document. So that the person can get an idea of ​​the digital declaration, preferably the digital recording information with the document, or a part of it, on the screen 2 is shown. With a sound recording it is played over a connected computer 1 not shown speaker, while the information is reasonable for the document on the screen. 1 If the person is satisfied with the digital declaration and this example signaled by pressing a button, it can be transmitted by the processor 15 via the network interface 21 and the external network to a network user or service. Any communication to a network user or service digital declaration may be checked by the latter on their validity. If the recording has little significance, the statement or the digital declaration is optionally rejected by the receiver.

In contracts or documents that require the consent of at least two over the network communicating those digital declarations can be each produced individually for the respective people and mutually delivered today. The digital declarations can ever be left alone. The document, which is the same in all these belong together digital declarations that connects the individual declarations together. If necessary, the individual digital declarations are combined into a common. This summary can be secured for example by a certified body with a digital signature.

It goes without saying that the processor 15 may encrypt the data transmitted via the external power digital declarations with a cryptographic algorithm. To increase the safety of the service by the digital declaration consent, the digital declaration and / or the digital recording of information and / or the document is preferably provided with a digital signature. To a known procedure for digitally signing is used. If the private key for the digital signature is present on a smart card 13a, so the same is read with the card reader. 13 By using the digital declaration in combination with the digital signature is achieved a very high degree of safety and liability. The combination combines the direct authenticity of the person with the authenticated assignment of a signature to that person. The security reaching exceeds an original signature.

To digitally sign a digital declaration different approaches are possible. According to a first procedure is determined by the document and the digital recording together, so from the digital declaration, a hash value and the digitally signed hash value. If a hash value is determined by the document and the digital recording each separately, these two hash values ​​can be signed together. According to a second approach, the digital signature of the receptacle is generated directly from the receiving device. In order to connect the intake and the document as a digital declaration securely with each other, also still a common digital signature thereof, generated by the recording and from the document, in particular of hash values. To secure the connection of the document with the receptacle, it is appropriate to sign something in common from the document and some of the recording. To connect a date safe with the digital declaration, a time stamp, in particular with the document and / or recording information is optionally digitally signed. Fig. 3 shows an example in which a mobile device such as a cell phone 22, via a radio link to a network, especially the Internet 6, will contact. It goes without saying that other mobile device may be used instead of a mobile phone 22, provided that connect to a network and make a time required for the digital recording declaration, or store data of such recording, and with the document can be processed into a digital declaration. A common mobile phone 22 includes a display 23, a keypad 24, a microphone 25 and a speaker 26. Now, if a Börsentransak- tion is to be triggered, for example, via the mobile phone 22 so it can be connected to a digital declaration. The display 23, the transaction is represented as a document. The person who wants to submit their agreement to the transaction with a digital declaration, says a text of the transaction into the microphone 25 and triggers by pressing a button to create the digital declaration of. Optionally, the digital declaration is submitted directly, or it is asked for the reproduction of the information used to create the digital declaration whether the digital declaration will now be sent. By the service or by a person to whom or which receives the digital declaration, the receipt of the declaration and, optionally, the acceptance of digital declaration can be confirmed. This confirmation can also take a digital declaration environmentally.

From the prior art it is known that a stock exchange transaction can be triggered by a telephone order. In this case, the telephone conversation by the recipient of the order is optionally recorded. Here it is not a digital declaration because the recording is made at the receiver, and because the combination of the digital recording with the document or with a marking of the document does not take place at the transmitter. It is essential for the digital declaration that the recording at the transmitter with the document will be connected. In order to prove that the compound of the recording is done with the document at the transmitter, preferably a digital signature method is used.

There are also already known mobile phone that include a digital camera 27th In the illustrated embodiment, the digital camera 27 is aligned or folded away connected to the mobile phone 22 and includes an inlet optics 27a and an operating member 27b. A recorded by the camera 27 image is preferably displayed on the display 23rd If, to create a digital declaration also an image-recording is to be used, the inlet optics is directed at the person 27a who wants to submit the agreement to a document or a transaction over the phone.
