Primary Accessory Device Encryption Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for encrypting/decrypting or hiding/unhiding content on devices have security concerns, such as reliance on fingerprint technology, complex password interactions, and ease of information leakage, with low overall security and convenience.
Innovation Solution
A method involving a primary device and an accessory device that binds through a communication protocol, detects operation instructions, and performs encryption or hiding based on preset instructions, with the accessory device participating in decryption or unhiding processes to enhance security and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint encryption methods are used, then security is improved, but hardware cost is increased
Solution Approach 1:
The encryption system is segmented into two parts: the primary device stores encrypted data, and the accessory device holds decryption credentials. This segmentation eliminates the need for expensive fingerprint sensors on the primary device while maintaining security through distributed trust.
Solution Approach 2:
The accessory device acts as an intermediary that holds the decryption key or credential. Instead of requiring the primary device to have complex biometric hardware, the system uses the accessory device as a mediator that can authenticate and enable decryption when paired with the primary device.
2Reliability
If password input encryption methods are used, then security is improved, but interaction complexity is increased
Solution Approach 1:
The binding between primary and accessory devices is performed in advance through a simplified pairing process. Once bound, the decryption credential is pre-configured, eliminating the need for complex password input during actual decryption operations.
Solution Approach 2:
The system enables self-service decryption where the accessory device automatically provides decryption capabilities once bound to the primary device. The user simply needs to have the accessory device present, without needing to manually input passwords or complex authentication sequences.
3Ease of operation
If gesture encryption methods are used, then ease of operation is improved, but security is worsened
Solution Approach 1:
The system segments authentication into two factors: possession of the accessory device and the pre-configured binding relationship. This is more secure than simple gestures while maintaining ease of operation, as the user only needs to have the accessory device with them.
Solution Approach 2:
The security parameter is changed from relying on complex gesture patterns to relying on the physical presence and binding relationship with the accessory device. This maintains user convenience while significantly improving security against unauthorized access.
4Device complexity
If only designated contents are encrypted, then device complexity is reduced, but adaptability is worsened
Solution Approach 1:
The binding module and decryption framework are designed to be universal, working with any type of content (files, messages, photos, videos) on the primary device. Once the accessory device is bound, it can decrypt any content that the primary device encrypts, providing broad adaptability without increasing complexity.

AI summary
In accordance with an aspect of the present disclosure, a method for encrypting/hiding or decrypting/unhiding a target object on a device is provided. The method comprises binding with a binding module; detecting an operation instruction for the target object; analyzing the detected operation instruction; outputting information to be confirmed for encrypting or hiding the target object if the detected operation instruction for the target object is a preset encryption instruction or a preset hiding instruction; and encrypting or hiding the target object after receiving a confirmation input.
