Abstract

End user license agreements included in a plurality of encrypted applications are extracted from the applications. In this way, acceptances of the end user license agreements are obtained from a user without waiting completion of decryption of the plurality of encrypted applications.

Claims

1. An application packaging device comprising:

a decrypting unit configured to individually decrypt a plurality of applications, each of which includes an end user license agreement;

a copying unit configured to copy the end user license agreement included in each decrypted application; and

a packaging unit configured to package the copy of each end user license agreement and the encrypted applications so as to obtain an application package.

2. The application packaging device according to claim 1, wherein the application package generation unit is configured to generate an application package in which the end user license agreements from the decrypted applications are included in a region of the application package distinct from the region including the encrypted applications.

3. The application packaging device according to claim 2,

wherein the application package generation unit also encrypts the copy of each end user license agreement.

4. The application packaging device according to claim 2,

wherein the application package generation unit calculates application definitions included in the decrypted applications, and generates an application package so that an application package definition obtained through the calculation is included in a region of the package distinct from the region corresponding to the encrypted applications.

5. The application packaging device according to claim 4,

wherein the application package generation unit determines whether addition or multiplication is used in accordance with types of information items included in the application definitions included in the decrypted applications.

6. A device comprising:

an obtaining unit configured to obtain end user license agreements from a region of an application package generated by the application packaging device according to claim 2 before a plurality of encrypted applications included in the application package are decrypted, the region including the agreements being distinct from the region including the encrypted applications; and

an installation unit configured to install the applications when acceptance of each end user license agreement is obtained from a user through an interface.

7. A device as claimed in claim 6, further comprising:

an obtaining unit configured to obtain an application package definition from a region of an application package generated by the application packaging device according to claim 4 before a plurality of encrypted applications included in the application package are decrypted, the region being distinct from the region including the encrypted applications; and

a determination unit configured to determine whether all of the applications included in the application package are installable in accordance with the obtained application package definition before the encrypted applications are decrypted.

8. The device of claim 6, arranged to generate an installation management table in accordance with information including the application definitions and the licenses.

9. The device of claim 8, wherein the device is arranged to detect if agreement to each license is obtained prior to making a determination as to whether all of the applications included in the application package are installable in accordance with the obtained application package definition.

10. The device of claim 6, wherein the device is arranged to ignore end user license agreements included in the encrypted applications.

12. A method for controlling an application installation device, comprising:

obtaining end user license agreements from a region of an application package generated by the application packaging device according to claim 2 before a plurality of encrypted applications included in the application package are decrypted, the region including the agreements being distinct from the region including the encrypted applications; and

installing the applications when acceptance of each end user license agreement is obtained from a user through an interface.

11. A method for controlling an application packaging device, comprising:

individually decrypting a plurality of applications, each of which includes an end user license agreement;

copying each end user license agreement; and

packaging the copy of each end user license agreement and the encrypted applications so as to obtain an application package.
