Token Access Validation Using Entity Characteristics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively validate network operations based on entity characteristics, leading to potential data breaches and poor user experiences due to malicious entities masking their identity, as they rely on entity identifiers that can be easily circumvented.
Innovation Solution
Implementing restricted access tokens bound to entity characteristics, determining item characteristics of accessed entities to ensure they align with the token's entity characteristics, using machine learning models and web scraping to validate access.

1Reliability
If access tokens are bound to entity identifiers, then access control can be implemented, but malicious entities can mask their identity by using semantically similar URLs or fake identifiers to circumvent validation
Solution Approach 1:
The patent changes the validation parameter from entity identifiers (URLs, names) to entity characteristics (categories, types, attributes). Instead of checking if the identifier matches, the system checks whether the entity's characteristics align with the token's bound characteristics. This parameter transformation makes it impossible for malicious entities to mask their identity through semantic similarity, as the validation is based on intrinsic characteristics rather than surface-level identifiers.
Solution Approach 2:
The patent replaces the mechanical string-matching mechanism (comparing identifiers directly) with a semantic validation mechanism (comparing characteristics against bound criteria). This substitution allows the system to understand the essence of an entity rather than just matching surface identifiers, thereby preventing circumvention through semantic similarity or fake identifiers.
2Ease of manufacture
If existing validation systems use entity identifiers for access control, then implementation is simple, but validation precision is insufficient and allows data breaches
Solution Approach 1:
The patent segments the validation process into distinct components: token issuance with bound entity characteristics, entity characteristic determination from item data, and validation comparison between the two. This segmentation allows each component to be optimized independently while achieving high validation precision. The system separates the simple token issuance from the complex characteristic analysis, maintaining ease of implementation while dramatically improving validation accuracy.
3Ease of operation
If tokens allow broad access to multiple third-party entities, then user convenience is improved, but security risks increase due to inability to restrict access based on entity characteristics
Solution Approach 1:
The patent introduces dynamic validation where each access request is evaluated against the token's bound entity characteristics in real-time. Instead of static allow/denial lists, the system dynamically determines whether the accessed entity's characteristics match the token's requirements. This dynamic approach maintains broad access convenience while preventing data breaches by blocking access to entities with mismatching characteristics, such as malicious or inappropriate entities.

AI summary
In some embodiments, validation of network operations related to use of a token via a token request based on entity characteristics may be facilitated. In some embodiments, a token request indicating use of a token to access an item associated with an entity may be detected, where the token is bound to one or more entity characteristics. Based on the token request, an entity identifier associated with the entity may be obtained. Using the entity identifier, one or more item characteristics of items available via the entity may be determined. Determining whether the entity satisfies the one or more entity characteristic to which the token is bound may be determined based on the one or more item characteristics. Access to the item associated with the entity may be validated based on the determination indicating that the entity satisfies the one or more entity characteristics to which the token is bound.
