Abstract

A system for application usage continuum across client devices and platforms includes a first client device configured to execute a first instance of an application and a second client device configured to execute a second instance of the application. The first client device is configured to receive an indication to transfer operation of the first instance of the application running on the first client device to the second instance of the application on the second client device. The first client device is further configured to generate state information and data associated with execution of the first instance of the application on the first client device and cause the state information to be sent to the second client device to enable the second instance of the application on the second client device to continue operation of the application on the second client device using the state information from the first client device.

Claims

1. A system for providing an application usage continuum across client devices, said system comprising:

a first client device configured to execute a first instance of an application;

a second client device configured to execute a second instance of said application; and

wherein, said first client device is further configured to;

receive an indication to transfer operation of said first instance of said application running on said first client device to said second instance of said application on said second client device;

generate state information and data associated with execution of said first instance of said application on said first client device; and

cause said state information to be sent to said second client device to enable said second instance of said application on said second client device to continue operation of said application on said second client device using said state information from said first client device.

2. The system of claim 1 further comprising a server configured to generate a private domain comprising an identity of each of said first and second client devices and an identity of said application.

3. The system of claim 2, wherein said server is configured to generate an application encryption key Ka for each of said first and second instances of said application and a domain encryption key P for said private domain and storing said domain encryption key P on each of said first and said second client devices.

4. The system of claim 3, wherein said first instance of said application is configured to encrypt or sign a state blob using said application key Ka to form an application-encrypted state blob (State)Ka, said (State)Ka comprising state information of said first instance of said application protected with said application key Ka.

5. The system of claim 4, wherein said second instance of said application is configured to decrypt or verify said (State)Ka and restore said state information on said second client device.

6. The system of claim 4, wherein said first client device comprises a secured processor configured to encrypt or sign said (State)Ka using said first client device and said domain encryption key P to form a domain-encrypted state blob ((State)Ka)P.

7. The system of claim 6, wherein said second device comprises a secured processor configured to decrypt said ((State)Ka)P using said second client device to form said (State)Ka.

8. The system of claim 1, wherein said state information comprises data corresponding to a timing counter, a video frame, or a page number.

9. The system of claim 1, wherein said indication to transfer operation of said first instance of said application comprises a user input.

10. The system of claim 9, wherein said user input is selected from a group consisting of gesture recognition, motion recognition, voice recognition and command, and proximity aware technologies.

11. A method for an application usage continuum between a first client device having a first instance of said application and a second client device having a second instance of said application, said method comprising:

receiving, on said first client device, an indication to transfer operation of said first instance of said application running on said first client device to said second instance of said application on said second client device;

generating, by said first client device and in response to said indication to transfer operation of said first instance of said application, state information and data associated with execution of said first instance of said application on said first client device; and

sending, by said first client device, said state information and data to said second client device to enable said second instance of said application on said second client device to continue operation of said application on said second client device using said second instance of said application and said state information from said first client device.

12. The method of claim 11 further comprising generating a private domain using a server, said private domain comprising an identity of each of said first and second client devices and an identity of said application.

13. The method of claim 12 further comprising:

generating an application encryption key Ka for each of said first and second instances of said application; and

generating a domain encryption key P for said private domain and storing said domain encryption key P on each of said first and said second client devices.

14. The method of claim 13, further comprising:

encrypting a state blob using said first instance of said application and said application key Ka to form an application-encrypted state blob (State)Ka, said (State)Ka comprising state information of said first instance of said application protected with said application key Ka; and

encrypting said (State)Ka using said first client device and said domain encryption key P to form a domain-encrypted state blob ((State)Ka)P.

15. The method of claim 14, further comprising:

decrypting said ((State)Ka)P using said second client device to form said (State)Ka; and

decrypting said (State)Ka using said second instance of said application;

wherein said second instance of said application is configured to restore said state information on said second client device.

16. The method of claim 11, wherein said state information comprises data corresponding to a timing counter, a video frame, or a page number.

17. The method of claim 11, wherein said indication to transfer operation of said first instance of said application comprises a user input.

18. The method of claim 17, wherein said user input is selected from a group consisting of gesture recognition, motion recognition, voice recognition and command, and proximity aware technologies.

20. The computer-readable medium of claim 16 further comprising:

receiving, on said first client device, an indication to transfer operation of said first instance of said application running on said first client device to said second instance of said application on said second client device.

19. A tangible computer-readable medium including instructions stored thereon which, when executed by one or more processors, cause the one or more processors to perform operations comprising:

generating, by one first client device and in response to the indication to transfer operation of the first instance of the application, state information and data associated with execution of the first instance of the application on the first client device; and

sending, by the first client device, the state information to the second client device to enable the second instance of the application on the second client device to continue operation of the application on the second client device using the state information from the first client device.
