Abstract

Methods and systems are provided for proxying data between an application server and a client device. One exemplary application system includes an application server to generate a virtual application and a proxy server coupled to the application server over a network to provide the virtual application to a client device. The proxy server receives input data from the client device and provides the input data to the application server, wherein the application server encodes the input data for an action in response to authenticating the proxy server and provides the data encoded for the action to the proxy server. The proxy server performs the action on the data and provides the result to the client device.

Claims

1. A method of storing data with an application server that preserves privacy of one or more data fields, the method including:

receiving, at a privacy proxy server, data representing a user input with first fields to be stored with an application server and at least one second field determined by the privacy proxy server to be encrypted based upon a rule indicating a type of data to encrypt and then stored by the application server;

forwarding the first fields, the second field encrypted, and a second field mark that indicates encryption of the second field to the application server to store;

the privacy proxy server querying the application server for a report that includes the second field encrypted and at least one of the first fields that has not been encrypted;

receiving from the application server the report comprising the at least one of the first fields in a report format and the second field encrypted with a report format placeholder;

decrypting the second field and replacing the report format placeholder with the decrypted second field; and

causing display of the report with the decrypted second field.

2. The method of claim 1, wherein decrypting the second field and replacing the report format placeholder includes the privacy proxy server detecting malicious code and performing a remedial action thereby preventing execution of the malicious code by a client.

3. The method of claim 1, wherein the report format placeholder identifies one or more post-decryption actions bypassed by the application server.

4. The method of claim 3, wherein the privacy proxy server performs the post-decryption actions on the decrypted second field.

5. The method of claim 1, wherein decrypting the second field and replacing the report format placeholder further includes distinguishing a unique identifier associated with the application server and utilizing the unique identifier to identify operators of code generated by the application server from potentially malicious code.

6. The method of claim 1, wherein encrypting the second field with the report format placeholder further includes marking the report format placeholder with a unique identifier associated with the application server.

7. The method of claim 1, wherein decrypting the second field and replacing the report format placeholder further includes distinguishing the second field from the report format placeholder based on an encoding authentication protocol established between the privacy proxy server and the application server.

13. A system including one or more processors coupled to memory, the memory loaded with computer instructions, the instructions, when executed on the processors, implement actions of claim 1.

8. A non-transitory, computer-readable medium storing computer executable instructions configured to cause a processor to perform operations including:

receiving, at a privacy proxy server, data representing a user input with first fields to be stored with an application server and at least one second field determined by the privacy proxy server to be encrypted based upon a rule indicating a type of data to encrypt and then stored by the application server;

forwarding the first fields, the second field encrypted, and a second field mark that indicates encryption of the second field to the application server to store;

querying the application server for a report that includes the second field encrypted and at least one of the first fields that has not been encrypted;

receiving from the application server the report comprising the at least one of the first fields in a report format and the second field encrypted with a report format placeholder;

decrypting the second field and replacing the report format placeholder with the decrypted second field; and

causing display of the report with the decrypted second field.

9. The computer-readable medium of claim 8, wherein decrypting the second field and replacing the report format placeholder includes the privacy proxy server detecting malicious code and performing a remedial action thereby preventing execution of the malicious code by a client.

10. The computer-readable medium of claim 8, wherein decrypting the second field and replacing the report format placeholder further includes distinguishing a unique identifier associated with the application server and utilizing the unique identifier to identify operators of code generated by the application server from potentially malicious code.

11. The computer-readable medium of claim 8, wherein encrypting the second field with the report format placeholder further includes marking the report format placeholder with a unique identifier associated with the application server.

12. The computer-readable medium of claim 8, wherein decrypting the second field and replacing the report format placeholder further includes distinguishing the second field from the report format placeholder based on an encoding authentication protocol established between the privacy proxy server and the application server.

14. A method of processing data stored with an application server that preserves privacy of one or more data fields, the method including:

receiving, from a privacy proxy server, data representing a user input with first fields and at least one encrypted second field to be stored at an application server, wherein the data includes a second field mark that indicates, to the application server, encryption of the second field;

storing, at the application server, the first fields and the at least one encrypted second field by the privacy proxy server based on a rule indicating a type of data to encrypt appropriate to an organization;

receiving, from the privacy proxy server, a query for a report that includes the encrypted second field and at least one of the first fields that has not been encrypted;

retrieving the at least one of the first fields and the second field responsive to the query;

using the application server to format the at least one of the first fields in a report format and to format the encrypted second field with a report format placeholder; and

forwarding the report for further computer-implemented processing.

15. The method of claim 14, wherein the report format placeholder identifies one or more post-decryption actions bypassed by the application server.

16. The method of claim 15, further including using the application server to generate code for a web page of a browser application running on a client device, wherein:

the code includes the encrypted second field within the web page; and

the encrypted second field is marked with at least one post-decryption action bypassed by the application server.

17. The method of claim 14, wherein using the application server to format the encrypted second field with the report format placeholder further includes marking the report format placeholder with a unique identifier associated with the application server.

18. The method of claim 14, wherein using the application server to encrypt the second field with the report format placeholder further includes:

hashing the report format placeholder to a hexadecimal representation; and

providing the hexadecimal representation as a parameter to a post-decryption function.

19. A non-transitory computer readable storage medium impressed with computer program instructions, the instructions, when executed on a processor, implement the method of claim 14.

20. A system including one or more processors coupled to memory, the memory loaded with computer instructions, the instructions, when executed on the processors, implement actions of claim 14.
