Content Identifier Specification for Secure Image Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require complex user operations for authenticating and restricting image browsing when transferring images from a digital camera to a smartphone or tablet, especially when the smartphone browses image data from a digital camera, leading to cumbersome processes for sharing specific images.
Innovation Solution
An information processing apparatus and method that allows for restricting image browsing by specifying accessible content identifiers using a second program, which sets parameters for a first program to manage user operations, enabling secure and simplified image transfer without complicating user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication processing is performed every time in security mode, then image browsing security is improved, but user operation complexity increases
Solution Approach 1:
The system performs preliminary authentication and sets accessibility information in advance. The digital camera stores accessibility information indicating which images can be browsed by external devices. When a smartphone connects, the image browsing program automatically retrieves this pre-set accessibility information and applies it without requiring user authentication, thus maintaining security while simplifying operation.
2Ease of operation
If all image data is made accessible to external devices, then ease of sharing is improved, but security control capability deteriorates
Solution Approach 1:
Instead of applying uniform access control to all images, the system applies different accessibility settings to different images. The digital camera stores accessibility information on a per-image basis, allowing the owner to specify which images are accessible to external devices and which are not. This enables selective sharing where some images are openly accessible while others remain protected.
Solution Approach 2:
The image browsing program acts as an intermediary between the smartphone and the digital camera's image database. It automatically acquires accessibility information from the digital camera and uses this information to control which images are displayed and transferred to the smartphone, eliminating the need for user authentication while maintaining security control.
3Reliability
If manual authentication is required for each image transfer, then security control capability is improved, but productivity deteriorates
Solution Approach 1:
The image browsing program automatically performs the security control function without requiring user authentication. It autonomously acquires accessibility information from the digital camera, determines which images can be browsed and transferred to the smartphone, and executes the transfer process. This self-service mechanism maintains security control capability while dramatically improving image transfer efficiency.

AI summary
An information processing apparatus connectable to a contents providing apparatus obtains a list of the identifiers of contents saved in the contents providing apparatus, and obtains accessibility information of the contents saved in the contents providing apparatus. Based on the obtained accessibility information, the information processing apparatus specifies at least one identifier of contents set to be accessible, among the identifiers of the obtained list. The information processing apparatus sets the specified identifier as parameters of a first program for accepting a user operation of designating the content. The information processing apparatus specifies the at least one identifier using a second program different from the first program.
