Encrypted file storage
View Patent ↗Various systems facilitate encrypted file storage. A client device may generate an encrypted version of a file. The client device may obtain at least one reference to at least one storage location for the encrypted version of the file. The client device may cause the encrypted version of the file to be store at the at least one storage location using the at least one reference to the at least one storage location.
1. A method of storing files that are associated with a user account in at least one cloud data storage provider, comprising:
receiving, by an index server, a request to store a first file on behalf of a user associated with access credentials of the user account, the request being received from a client device executing a file management application that communicates with the index server;
identifying, by the index server, a first storage location of the first file associated with a cloud data storage provider that is different from the index server; and
providing, by the index server, the first storage location to the file management application, the first storage location specifying where to send an encrypted version of the first file, the encryption being based on a first key associated with the first storage location of the first file, the first key being different than the access credentials for the cloud data storage provider.
2. The method of claim 1 , further comprising:
receiving, at the index server, a request from the client device to access the file;
determining the client device is authorized to access the file; and
providing the first storage location to the client device for retrieving the encrypted file for decryption by the file management application using the first key.
3. The method of claim 1 , further comprising:
receiving the first key from the client device;
receiving a request from the client device to access the file; and
sending, to the client device, a version of the first key for decrypting the encrypted first file.
4. The method of claim 1 , further comprising:
sending a management component to the client device for installation, wherein the management component causes the first key to be deleted from the client device after the encrypting.
5. The method of claim 1 , further comprising:
receiving, by the index server, a request to store a second file;
identifying, by the index server, a second storage location unassociated with the cloud data storage provider; and
providing the second storage location to the file management application, wherein the file management application encrypts the second file based on a second key associated with the second storage location and sends the encrypted second file to second storage location using access credentials associated with the second storage location.
6. The method of claim 5 , wherein the second storage location is at the index server.
7. The method of claim 1 , wherein the wherein the file management application requests the first key for decrypting the encrypted file.
8. A system of storing files that are associated with a user account in at least one cloud data storage provider, comprising:
a non-transitory, computer-readable medium containing instructions; and
a processor device for an index server that executes the instructions to perform stages comprising:
receiving, by the index server, a request to store a first file on behalf of a user associated with access credentials of the user account, the request being received from a client device executing a file management application that communicates with the index server;
identifying a first storage location of the first file associated with a cloud data storage provider that is different from the index server; and
providing, by the index server, the first storage location to the file management application, the first storage location specifying where to send an encrypted version of the first file, the encryption being based on a first key associated with the first storage location of the first file, the first key being different than the access credentials for the cloud data storage provider.
9. The system of claim 8 , the stages further comprising:
receiving, at the index server, a request from the client device to access the file;
determining the client device is authorized to access the file; and
providing the first storage location to the client device for retrieving the encrypted file for decryption by the file management application using the first key.
10. The system of claim 8 , the stages further comprising:
receiving the first key from the client device;
receiving a request from the client device to access the file; and
sending, to the client device, a version of the first key for decrypting the encrypted first file.
11. The system of claim 8 , the stages further comprising:
sending a management component to the client device for installation, wherein the management component causes the first key to be deleted from the client device after the encrypting.
12. The system of claim 8 , the stages further comprising:
receiving, by the index server, a request to store a second file;
identifying, by the index server, a second storage location unassociated with the cloud data storage provider; and
providing the second storage location to the file management application, wherein the file management application encrypts the second file based on a second key associated with the second storage location and sends the encrypted second file to second storage location using access credentials associated with the second storage location.
13. The system of claim 12 , wherein the second storage location is at the index server.
14. The system of claim 8 , wherein the wherein the file management application requests the first key for decrypting the encrypted file.
15. A non-transitory, computer-readable medium containing instructions for storing files that are associated with a user account in at least one cloud data storage provider, the instructions being executed by a processor device to perform stages comprising:
receiving, by the index server, a request to store a first file on behalf of a user associated with access credentials of the user account, the request being received from a client device executing a file management application that communicates with the index server;
identifying a first storage location of the first file associated with a cloud data storage provider that is different from the index server; and
providing, by the index server, the first storage location to the file management application, the first storage location specifying where to send an encrypted version of the first file, the encryption being based on a first key associated with the first storage location of the first file, the first key being different than the access credentials for the cloud data storage provider.
16. The non-transitory, computer-readable medium of claim 15 , the stages further comprising:
receiving, at the index server, a request from the client device to access the file;
determining the client device is authorized to access the file; and
providing the first storage location to the client device for retrieving the encrypted file for decryption by the file management application using the first key.
17. The non-transitory, computer-readable medium of claim 15 , the stages further comprising:
receiving the first key from the client device;
receiving a request from the client device to access the file; and
sending, to the client device, a version of the first key for decrypting the encrypted first file.
18. The non-transitory, computer-readable medium of claim 15 , the stages further comprising:
sending a management component to the client device for installation, wherein the management component causes the first key to be deleted from the client device after the encrypting.
19. The non-transitory, computer-readable medium of claim 15 , the stages further comprising:
receiving, by the index server, a request to store a second file;
identifying, by the index server, a second storage location unassociated with the cloud data storage provider; and
providing the second storage location to the file management application, wherein the file management application encrypts the second file based on a second key associated with the second storage location and sends the encrypted second file to second storage location using access credentials associated with the second storage location.
20. The non-transitory, computer-readable medium of claim 19 , wherein the second storage location is at the index server.
