Systems and methods for data encryption and decryption

A mobile user device, comprising:

• a non-transitory memory;
• and
• one or more hardware processors configured to execute instructions to cause the mobile user device to perform operations comprising:
• determining that the mobile user device is connected to a second computing device;
• responsive to determining that the mobile user device is connected to the second computing device, accessing a virtual storage area that is displayed to a user of the second computing device as part of storage space on the mobile user device, wherein the virtual storage area redirects a read or write request directed at the virtual storage to corresponding storage space on the second computing device;
• detecting a first request by a user of the second computer device to read first data identified to the user as stored in the virtual storage area;
• responsive to detecting the first request to read first data displayed to the user as stored in the virtual storage area, transmitting the first data, from a storage area on the second computing device, to the mobile user device;
• decrypting, using the mobile user device, the first data to produce first decrypted data;
• transmitting the first decrypted data from the mobile user device to the second computing device;
• providing the first decrypted data for access, on the second computing device, by the first request;
• detecting a second request by a user of the second computer device to write second data to the virtual storage area;
• responsive to detecting the second request to write second data to the virtual storage area, transmitting the second data from the second computing device to the mobile user device;
• encrypting, using the mobile user device, the second data to produce second encrypted data;
• transmitting the second encrypted data from the mobile user device to the second computing device;
• and
• storing the second encrypted data on the second computing device.

A first device, comprising:

• a non-transitory memory;
• and
• one or more hardware processors configured to execute instructions to cause the first device to perform operations comprising:
• determining that the first device is connected to a second computing device;
• responsive to determining that the first device is connected to the second computing device, accessing a virtual storage area that is identified to a user of the second computing device as part of storage space on the first device, wherein the virtual storage area redirects a read or write request directed at the virtual storage to corresponding storage space on a third computing device that is separate from the first device and from the second computing device;
• detecting a first request by a user of the second computer device to read first data identified to the user as stored in the virtual storage area;
• responsive to detecting the first request to read first data identified to the user as stored in the virtual storage area, transmitting the first data, from a storage area on the third computing device, to the device;
• decrypting, using the first device, the first data to produce first decrypted data;
• transmitting the first decrypted data from the first device to the second computing device;
• providing the first decrypted data for access, on the second computing device, by the first request;
• detecting a second request by a user of the second computer device to write second data to virtual storage area;
• responsive to detecting the second request to write the second data to the virtual storage area, transmitting the second data from the second computing device to the first device;
• encrypting, using the first device, the second data to produce second encrypted data;
• transmitting the second encrypted data from the device to the third computing device;
• and
• storing the second encrypted data on the third computing device.
