Ephemeral Content Sharing via Dynamic Token Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing social networking services face challenges in managing content distribution to specific individuals, balancing user privacy with data monetization, and providing flexible content deletion options, leading to user frustration due to long-lived and inaccessible content.
Innovation Solution
An electronic device with an interface circuit, imaging sensor, memory, and processor generates secure content based on protection information, allowing selective sharing and un-sharing through unique tokens, enabling long-lived but ephemeral access to content, enhancing user control and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If content is made long-lived and accessible on social networking services, then content availability and user engagement are improved, but user privacy control and ability to delete content are worsened
Solution Approach 1:
The patent implements dynamic content access control through token-based authorization, where content availability transitions from static permanent access to dynamic conditional access. Tokens are generated with specific expiration times and access conditions, allowing the system to adapt content accessibility over time while maintaining automated control.
Solution Approach 2:
The patent introduces tokens as intermediary objects between content and users. These tokens act as mediators that control access to content without requiring direct user intervention for each access request. The token system enables automated content distribution while maintaining privacy control through programmable access rules and expiration mechanisms.
2Object-affected harmful factors
If automatic deletion of content is implemented after short fixed time, then content privacy is improved, but content accessibility and user control flexibility are worsened
Solution Approach 1:
The system implements dynamic content lifecycle management where content expiration and accessibility are determined by programmable rules rather than fixed time intervals. Tokens can be configured with different expiration times, renewal conditions, and access policies, allowing the system to adapt to different privacy requirements while maintaining automated control.
Solution Approach 2:
The patent changes the parameter of content expiration from fixed time-based deletion to flexible token-based access control. Tokens can be configured with various parameters including expiration time, renewal conditions, and access restrictions, enabling the system to adjust content availability based on different scenarios while maintaining automated management.
3Productivity
If content is shared with multiple people in social networks, then content distribution capability is improved, but management complexity and privacy control difficulty are worsened
Solution Approach 1:
The patent uses tokens as intermediary objects to manage content distribution to multiple users. Instead of managing individual permissions for each user, the system generates tokens that can be distributed to multiple recipients with pre-configured access rules. This token-based approach simplifies the management of content sharing across social networks while maintaining granular privacy control.
Solution Approach 2:
The system segments content access control into token-based units, where each token represents a specific access permission set. This segmentation allows the system to manage content distribution to multiple users independently through separate tokens, reducing the overall management complexity while maintaining fine-grained control over each recipient's access rights.
Data Source
AI summary
An electronic device that provides long-lived, but selectively ephemeral access to content is described. In particular, the electronic devices may provide secure content, which was generated based on protection information and the content, to a computer system. After receiving a share command, the electronic device may communicate, to the computer system, a unique token that is associated with a recipient in a communication network and an instruction to enable a recipient electronic device associated with the recipient to view the content. This unique token may allow the computer system to access the content in the secure content, so that the computer system has an ability to provide the content to the recipient electronic device. Moreover, after receiving an un-share command, the electronic device may temporarily or permanently disable the unique token on the computer system, so that the computer system is unable to access the content in the secure content.
