Abstract

A method for the separate authentication of a template and of data inserted therein. A template is provided with a template ID and a template Data Authentication Code (DAC(t)). User data is inserted in the template, and then extracted to be handled separately. A DAC(d) is generated on the user data by itself, and stored in an Approval Data packet with the template ID, DAC(t) and the user data. The complete document with the template and the user data can later be reconstructed. The method may be useful for many industries that rely on templates as a means for collecting data.

Claims (25)

1. A method for the separate authentication of a template and of user data inserted therein, comprising the steps of:

c) extracting the user data from the template;
d) generating a user data Document Authentication Code, hereinafter referred to as DAC(d), based on the user data; and e) storing the template ID, DAC(t), the user data and DAC(d) in an Approval Data Packet, hereinafter referred to as ADP.
2. The method according to claim 1, wherein step a) comprises the substeps of:
i) generating the template;
ii) creating the template ID;
iii) creating DAC(t); and iv) storing the template ID and DAC(t) in a location linked to the template.
3. The method according to claim 2, wherein substep a)iii) comprises generating DAC(t) from a one-way hash function.
4. The method according to claim 2, wherein, in substep a) iv), the location linked to the template is inside said template.
5. The method according to claim 2, wherein, in substep a) iv), the location linked to the template is a linked storage system.
6. The method according to claim 1, wherein step e) further comprises encrypting the ADP.
7. The method according to claim 1, further comprising an additional step f) of reconstructing an authenticated complete document, said complete document including the template and the user data.
8. The method according to claim 7, wherein step f) comprises the substeps of:
i) retrieving the template ID and DAC(t) from the ADP;
ii) opening the template corresponding to said template ID;
iii) generating for said template a new template Document Authentication Code, hereinafter referred to as DAC(nt);
iv) comparing DAC(nt) with DAC(t), and proceeding only if DAC(nt) is equal to DAC(t);
v) retrieving the user data and DAC(d) from the ADP;
vi) generating for said user data a new user data Document Authentication Code, hereinafter referred to as DAC(nd);
vii) comparing DAC(nd) with DAC(d), and proceeding only if DAC(nd) is equal to DAC(d); and viii) inserting the user data in the template.
9. The method according to claim 1, wherein the template has entry fields, and wherein said step of inserting user data includes the step of inserting user data into said entry fields.
10. The method according to claim 9, wherein step b) further comprises prompting the user for the user data.
11. The method according to claim 9, wherein step e) further comprises encrypting the ADP.
12. The method according to claim 9, further comprising an additional step f) of reconstructing an authenticated complete document, said complete document including the template and the user data.
13. The method according to claim 12, wherein step f) comprises the substeps of:
i) retrieving the template ID and DAC(t) from the ADP;
ii) opening the template corresponding to said template ID;
iii) generating for said template a new template Document Authentication Code, hereinafter referred to as DAC(nt);
iv) comparing DAC(nt) with DAC(t), and proceeding only if DAC(nt) is equal to DAC(t);
v) retrieving the user data and DAC(d) from the ADP;
vi) generating for said user data a new user data Document Authentication Code, hereinafter referred to as DAC(nd);
vii) comparing DAC(nd) with DAC(d), and proceeding only if DAC(nd) is equal to DAC(d); and viii) inserting the user data in the template.
14. The method according to claim 1, wherein said method further includes step b1) generating a complete Document Authentication Code, hereinafter referred to as DAC(c), based on the template with the user data therein.
15. The method according to claim 14, wherein step a) comprises the substeps of:
i) generating the template;

ii) creating the template ID;
iii) creating DAC(t); and iv) storing the template ID and DAC(t) in a location linked to the template.
16. The method according to claim 15, wherein substep a)iii) comprises generating DAC(t) from a one-way hash function.
17. The method according to claim 15, wherein, in substep a) iv), the location linked to the template is inside said template.
18. The method according to claim 15, wherein, in substep a) iv), the location linked to the template is a linked storage system.
19. The method according to claim 14, wherein step f) further comprises encrypting the ADP.
20. The method according to claim 14, further comprising an additional step g) of reconstructing an authenticated complete document, said complete document including the template and the user data.
21. The method according to claim 20, wherein step g) comprises the substeps of:
i) retrieving the template ID, DAC(t) and DAC(c) from the ADP;
ii) opening the template corresponding to said template ID;

iii) generating for said template a new template Document Authentication Code, hereinafter referred to as DAC(nt);
iv) comparing DAC(nt) with DAC(t), and proceeding only if DAC(nt) is equal to DAC(t);
v) retrieving the user data and DAC(d) from the ADP;
vi) generating for said user data a new user data Document Authentication Code, hereinafter referred to as DAC(nd);
vii) comparing DAC(nd) with DAC(d), and proceeding only if DAC(nd) is equal to DAC(d);
viii) inserting the user data in the template;
ix) generating for the template with the user data therein a new complete document Document Authentication Code, hereinafter referred to as DAC(nc); and x) comparing DAC(nc) with DAC(c), and proceeding only if DAC(nc) is equal to DAC(c).
22. The method according to claim 20, wherein step g) comprises the substeps of:
i) retrieving the template ID, the user data and DAC(c) from the ADP;
ii) opening the template corresponding to said template ID;

iii) inserting the user data in the template;
