Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing apparatuses face challenges in sharing face feature amount data due to differences in face authentication function types between devices, leading to incompatible data formats and the need for re-generation of feature data.
Innovation Solution
An information processing apparatus that communicates with external devices, acquiring and comparing face authentication function types to determine whether to use or re-generate face feature amount data, ensuring compatibility and seamless data sharing across different face authentication modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If face feature amount data is shared between apparatuses with different face authentication function types, then data compatibility is improved, but data format inconsistency causes authentication failure
Solution Approach 1:
The patent applies parameter changes by detecting the face authentication function type of the external apparatus and changing the data format parameters of the face feature amount data accordingly. When the external apparatus uses a different face authentication function type, the system converts the data format to match the external apparatus's requirements, ensuring both compatibility and authentication accuracy.
2Reliability
If face feature amount data is re-generated for different face authentication modules, then authentication accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-detecting and storing information about the face authentication function types of connected apparatuses. This allows the system to prepare the appropriate data format in advance before actual face authentication is needed, reducing processing time during the authentication process while maintaining accuracy.
Solution Approach 2:
The system dynamically adjusts the face feature amount data format based on the detected face authentication function type of the external apparatus. Rather than using a static data format, the system changes the data structure dynamically to match the requirements of the specific authentication module being used, optimizing both accuracy and efficiency.
3Productivity
If face feature amount data is directly used without format conversion, then processing speed is improved, but data format incompatibility prevents successful authentication
Solution Approach 1:
The patent introduces an intermediary conversion process that mediates between different face authentication function types. The system includes a data conversion module that acts as an intermediary, automatically transforming face feature amount data between different formats based on the detected authentication module type, enabling compatibility without sacrificing processing efficiency.

AI summary
An information processing apparatus which communicates with an external apparatus having a face authentication function, comprises a unit which acquires a type of the authentication function of the external apparatus from the external apparatus; a unit which receives image data held in the external apparatus and a face feature amount used by the external apparatus for the authentication function; and a unit which controls, in accordance with a result of comparing a type of a face authentication function of the information processing apparatus with the type of the authentication function of the external apparatus, whether to use the received face feature amount for the authentication function of the information processing apparatus, or to re-generate, from the received image data, a face feature amount corresponding to the type of the authentication function of the information processing apparatus.
