Computerized method and system for managing secure content sharing in a networked secure collaborative exchange environment with customer managed keys
In embodiments of the present invention, improved capabilities are described for securely sharing computer data content between business entities as managed through an intermediate business entity, where the secure sharing process utilizes encryption provided by the intermediate business entity but where the encryption keys used in the encryption are at least in part managed through one of the business entities as customer managed keys.
1. A method for managing a networked secure collaborative computer data exchange environment, the method comprising:
establishing, by a secure exchange server managed by an intermediate business entity, a user login data authentication procedure that allows a user through at least one client computing device to access the secure exchange server, wherein the user is one of a plurality of users of a plurality of other business entities and communications between the secure exchange server and the plurality of users is through a communications network;
storing, by the secure exchange server, at least one user login authentication data for at least one of the plurality of users;
receiving at the exchange server a computer data content from a first of the plurality of users, wherein the first of the plurality of users permits a sharing access to the computer data content to at least a second of the plurality of users, and wherein management for access to the computer data content is through an exchange content access facility managed by the intermediate business entity, wherein at least one of the plurality of other business entities manages its own encryption keys for use in encrypting computer data content;
granting, by the secure exchange server, sharing access to the computer data content to the at least second of the plurality of users when the secure exchange server receives from the second of the plurality of users its client login authentication data provided that the second of the plurality of users is one of the subset of the plurality of users to which sharing access is permitted;
receiving a request from the at least second of the plurality of users to access a copy of the computer data content;
granting, by the secure exchange server, the copy access request to the at least second of the plurality of users, wherein a copy of the computer data content is made;
receiving from the first of the plurality of users a request to revoke sharing access to the computer data content to the at least second of the plurality of users;
revoking, by the secure exchange server, sharing access to the computer data content to the at least second of the plurality of users; and
deleting access, by the secure exchange server, to the copy of the computer data content made by the at least second of the plurality of users.
2. The method of claim 1 , wherein the plurality of other business entities manages their own encryption keys for use in encrypting the computer data content.
3. The method of claim 1 , wherein the exchange content access facility managed by the intermediate business entity interfaces with a key management facility of at least one of the other business entities by which the other business entity manages its own encryption keys for encrypting and decrypting the computer data content to facilitate the sharing access.
4. The method of claim 1 , further comprising additional sharing of the computer data content within the plurality of users, wherein the revoking of sharing access to the computer data content revokes access to all instances of the shared computer data content and all copies of the computer data content made by the plurality of users.
5. The method of claim 1 , wherein the copy of the computer data content is stored on the secure data server.
6. The method of claim 5 , wherein the copy of the computer data content is deleted from the secure data server.
7. The method of claim 5 , wherein the deleting access to the computer data content makes the computer data content inaccessible to the at least the second of the plurality of users.
8. The method of claim 1 , wherein the copy of the computer data content is stored on a client computing device by the at least second of the plurality of users.
9. The method of claim 8 , wherein the deleting access to the copy of the computer data content is revocation of digital rights management of the computer data content.
10. The method of claim 9 , wherein the revocation of the digital rights management of the computer data content is made by the first of the plurality of users.
11. The method of claim 1 , wherein the computer data content is at least one of a word processor document, a spreadsheet document, and a presentation document.
12. The method of claim 1 , wherein the computer data content is at least one of an email, a text, and a blog entry.
13. The method of claim 1 , wherein the computer data content is a multimedia file.
14. The method of claim 1 , wherein the computer data content is a secure encrypted computer data content.
15. The method of claim 1 , wherein the computer data content is viewed by the at least second of the plurality of client users through a secure viewing facility.
16. The method of claim 1 , wherein the at least second of the plurality of users is connected to a public network that is outside of the firewall for the business entity that manages the first or second of the plurality of users.
17. The method of claim 1 , wherein the at least second of the plurality of users accesses the computer data content through a personal computing device that is not owned by the business entity that manages the at least second of the plurality of users.
18. The method of claim 1 , wherein the at least second of the plurality of users accesses the computer data content through a mobile computing device.
19. The method of claim 1 , wherein the exchange content access facility is interfaced through a dashboard facility accessible though at least the first of the plurality of users.
20. The method of claim 19 , wherein the dashboard facility provides reports showing activity related the sharing of computer data content.
21. The method of claim 19 , wherein the dashboard facility is accessible through third-party environments.
22. The method of claim 19 , wherein the dashboard facility tracks the location and version of the shared computer data content on computing devices accessible by the at least second of the plurality of users.
23. The method of claim 1 , wherein the communications network is the Internet.
