Abstract
Systems, methods and computer readable media for providing users with encrypted content data associated with a service are disclosed. A device may receive first content data. The device may encrypt the first content data using a first key to obtain first encrypted data. The device may generate second encrypted data by applying a cipher substitution to the first encrypted data using a second key. The device may cause to send the second encrypted data to a second device.
Claims20
A device comprising:
- at least one computer processor;
- and
- at least one storage medium storing computer-executable code comprising:
- receiving first content data;
- encrypting the first content data using a first key to obtain first encrypted data;
- generating second encrypted data by applying a cipher substitution to the first encrypted data using a second key;
- and
- causing to send the second encrypted data to a second device.
5 more elements
A device, comprising:
- at least one computer processor;
- and
- at least one storage medium storing computer-executable code comprising:
- receiving first encrypted data;
- determining a first index value;
- determining a first key based on the first index value;
- generating second encrypted data by applying a cipher substitution to the first encrypted data using the first key;

7 more elements
A method comprising:
- receiving, by one or more processors, first content data;
- encrypting, by the one or more processors, the first content data using a first key to obtain first encrypted data;
- generating, by the one or more processors, second encrypted data by applying a cipher substitution to the first encrypted data using a second key;
- and
- causing to send, by the one or more processors, the second encrypted data to a device.
