Abstract
A content generation apparatus capable of allowing a user to select an image file to be used according to a purpose. In the content generation apparatus, one or more controllers function to generate a content, generate metadata including original comparison information for grasping a change from a generation time point of a content file including the content, generate a hash value on a basis of the metadata including the original comparison information and of the content, generate a first content file which includes the content, the metadata including the original comparison information, and the hash value, and generate a second content file which includes the content and does not include the original comparison information.
Claims17
A content generation apparatus comprising:
- one or more controllers configured to function as:
- a unit configured to generate a content;
- a unit configured to generate metadata including original comparison information for grasping a change from a generation time point of a content file including the content;
- a unit configured to generate a hash value on a basis of the metadata including the original comparison information and of the content;
- a unit configured to generate a first content file which includes the content, the metadata including the original comparison information, and the hash value;
- and
- a unit configured to generate a second content file which includes the content and does not include the original comparison information.
A control method of a content generation apparatus,
- the control method comprising:
- a step of generating a content;
- a step of generating metadata including original comparison information for grasping a change from a generation time point of a content file including the content;
- a step of generating a hash value on a basis of the metadata including the original comparison information and of the content;
- a step of generating a first content file which includes the content, the metadata including the original comparison information, and the hash value;
- and
- a step of generating a second content file which includes the content and does not include the original comparison information.
A computer-readable non-transitory storage medium storing a program for executing a method for controlling a content generation apparatus, the control method comprising:
- a step of generating a content;
- a step of generating metadata including original comparison information for grasping a change from a generation time point of a content file including the content;
- a step of generating a hash value on a basis of the metadata including the original comparison information and of the content;
- a step of generating a first content file which includes the content, the metadata including the original comparison information, and the hash value;
- and
- a step of generating a second content file which includes the content and does not include the original comparison information.
