Abstract

The present invention avoids execution of processing not intended by the user on the photographed image in a locked state. The image photographed by a camera which is in a lock released state is stored in a user area created in a storage area. On the other hand, an image photographed by a camera, which turned to a locked state as a result of being performed no operation for more than a fixed time, is stored in an area where stores the photographed image photographed in a locked state (second storage area). The image stored in the second storage area is determined after an input of a user's instruction with regard to the processing to be performed on the image.

First claim

What is claimed is:

1 . An information processing apparatus capable of obtaining data in either a first state in which feature or operation is restricted or a second state in which the restriction is released, the information processing apparatus comprising:
a determining unit configured to determine whether the data is obtained in the first state or in the second state, a storing unit configured to individually store first data obtained in the first state and second data obtained in the second state in a predetermined storage medium; and a control unit configured to determine processing to be performed on data stored in the storage medium after an input of a predetermined instruction.

2 . The information processing apparatus according to claim 1 , wherein:
the first data represents a first photographed image obtained by an imaging unit which allows photographing by a user, the second data represents a second photographed image obtained by the imaging unit in a state in which the restriction is released, and the storing unit is further configured to store the first photographed image in a storage area where is different from where the second photographed image is stored.

3 . The information processing apparatus according to claim 1 ,
wherein the storing unit is further configured to store information at the time of photographing, representing that the first photographed image is photographed in the first state, in relation with the first photographed image.

4 . The information processing apparatus according to claim 2 ,
wherein the control unit is further configured to receive processing content to be executed on the first photographed image as the input of the instruction, to execute the processing content received, and to store information representing “processed” after executing the processing content in relation with the first photographed image.

5 . The information processing apparatus according to claim 4 ,
wherein a first storing area for storing the first photographed image and a second storage area where is different from the first storing area are created in the storage medium, and wherein the control unit is further configured to execute:
(1) processing to move the first photographed image stored in the first storing area to the second storage area; or
(2) processing to remove the first photographed image from the first storage area.

6 . The information processing apparatus according to claim 5 ,
wherein the second storage area is assigned for each user, and the control unit is further configured to receive the input of the instruction for each user and execute processing to move the first photographed image to the second storage area assigned for the user.

7 . The information processing apparatus according to claim 6 , further comprising a managing unit configured to hold account information of a plurality of users who are allowed to log in,
wherein the control unit is further configured to compare the account information obtained before the apparatus turns to the first state and the account information obtained after the first state is released, and hold the processing to be performed on the first photographed image if the account information do not match.

8 . The information processing apparatus according to claim 1 ,
wherein the first state is a state in which user's authentication is required when restarting the feature or operation of the imaging unit and the second state is a state in which the authentication is succeeded.

9 . An imaging device which allows photographing by a user in either a first state in which feature or operation is restricted or in a second state in which the restriction is released, the imaging device comprising:
a determining unit configured to determine whether the imaging unit at the time of photographing is in the first state or in the second state; a storing unit configured to individually store a first photographed image photographed when the imaging unit is in the first state and a second photographed image photographed when the imaging unit is in the second state in a predetermined storage medium; a display unit configured to display an operation screen for operating the first photographed image; a control unit configured to receive processing content to be executed on the first photographed image input by the user through the operation screen and to execute the processing content received.

10 . An information processing apparatus comprising:
a giving unit configured to give tamper resistant to first data obtained in a feature restricted state; a generation unit configured to generate alternate data, which is alternative to the first data; a control unit configured to present the alternate data to an access source to the first data and enable presentation of the first data after an input of an user's instruction associated with the presentation; a memory unit configured to separately store the second data obtained in a state with no feature restriction from the first data; and a meta-information obtaining unit configured to obtain first meta-information accompanying the first data or second meta-information accompanying the second data, wherein the control unit is further configured to present the second data and the second meta-information to an access source to the second data, wherein, to the access source to the first data, the first data and the first meta-information instructed by the user are presented when presentation of the first data is enabled.

11 . The information processing apparatus according to claim 10 ,
wherein the giving unit is further configured to give the tamper resistant to the first data by encrypting the first data using key information to which no access from the access source is allowed.

12 . The information processing apparatus according to claim 10 ,
wherein the giving unit is further configured to give the tamper resistant to the first data by storing the first data in a storage area to which no access from the access source is allowed.

13 . The information processing apparatus according to claim 10 ,
wherein the access source represents an application which requests to obtain the first data or the second data and executes subsequent processing after obtaining result of the request, and wherein the control unit is further configured to output the information prompting to input the instruction to the user independently of the application after presenting the alternate data to the application in response to the request to obtain the first data.

14 . The information processing apparatus according to claim 13 , further comprising:
a policy holding unit configured to hold security policy for defining apparatus features which are available/unavailable to the application, wherein the generation unit is further configured to vary the content of the alternate data to be generated depending on the security policy.

15 . The information processing apparatus according to claim 14 ,
wherein the generation unit is further configured to generate dummy image which recalls the first data as the alternate data in a case where use of the apparatus feature to output the first data outside the apparatus is not allowed by the security policy.

16 . The information processing apparatus according to claim 14 ,
wherein the generation unit is further configured to generate dummy image which is irrelevant to the first data as the alternate data in a case where use of the apparatus feature to output the first data outside the apparatus is allowed by the security polic
