Abstract
There is provided an information processing apparatus. An acquisition unit acquires feature information of a latest block in a block chain when target data is generated. A registration unit registers proof information indicating that the generated target data is correlated with the feature information acquired by the acquisition unit when the target data is generated to a time proof service.
Claims7
An information processing apparatus comprising:
- an acquisition unit that acquires feature information of a latest block in a block chain when target data is generated;
- and
- a registration unit that registers proof information indicating that the generated target data is correlated with the feature information acquired by the acquisition unit when the target data is generated to a time proof service.
A non-transitory computer readable medium storing a program causing a computer to execute information processing, the information processing comprising:
- acquiring feature information of a latest block in a block chain when target data is generated;
- and
- registering proof information indicating that the generated target data is correlated with the feature information which is acquired when the target data is generated to a time proof service.
A non-transitory computer readable medium storing a program causing a computer to execute information processing, the information processing comprising:
- when target data, feature information of a latest block that is acquired from a block chain when the target data is generated, and proof information indicating that the target data and the feature information are correlated with each other are obtained,
- acquiring time information of a block corresponding to the feature information from the block chain and that sets the time information to a first time point;
- acquiring time information of a block that includes the proof information from the block chain and sets the time information to a second time point;
- and
- presenting information indicating that the target data is generated in a period between the first time point and the second time point.
