Abstract
There is provided systems and methods for data feature extraction based on feedback from a network. The system may be used generally to enable feature-specific network operations, including one or more of access control, data compression and selective encryption. Further, embodiments provide methods and systems for data compression based on feature similarity and may include privacy protection.
Claims20
A system for feature extraction, the system comprising a feature extraction router and a feature validation center, wherein each of the feature extraction router and the feature validation center have one or more associated memories storing instructions, wherein execution of the instructions by one or more associated processors results in:
- the feature extraction router being configured to:
- receive a request for feature extraction from a data consumer;
- extract a data feature in response to the request;
- and
- send the data feature to the feature validation center;
- and
- the feature validation center being configured to:
- determine whether the data feature belongs to a feature set, wherein the feature set includes existing data features provided by a third party off-line;
- upon determination that the data feature does not belong to the feature set, generate a feedback which indicates potential data features, wherein the potential data features are associated with the data feature and the existing data features and send the feedback to the feature extraction router to re-extract a new data feature;
- and
- upon determination that the data feature belongs to the feature set, trigger feature-enabled network operations at least in part based on a set of valid data features, the set of valid data features is associated with the feature set and the data feature.
8 more elements
A method for feature extraction, the method comprising:
- receiving, by a feature extraction router, a request for feature extraction from a data consumer;
- extracting, by the feature extraction router, a data feature in response to the request;
- determining, by the feature validation center, whether the data feature belongs to a feature set, wherein the feature set includes existing data features provided by a third party off-line;
- upon determination that the data feature does not belong to the feature set, generating, by the feature validation center, feedback which indicates potential data features, wherein the potential data features are identified from or associated with the data feature and the existing data features and sending, by the feature validation center, the feedback to the feature extraction router to re-extract a new data feature;
- and
- upon determination that the data feature belongs to the feature set, triggering, by the feature validation center, feature-enabled network operations at least in part based on a set of valid data features, the set of valid data features associated with the feature set and the data feature.
3 more elements
A method for data feature validation, comprising:
- receiving, by a feature validation center, a data feature from a feature extraction router;
- determining, by the feature validation center, whether the data feature belongs to a feature set, wherein the feature set includes existing data features provided by a third party off-line;
- upon determination that the data feature does not belong to the feature set, generating, by the feature validation center, feedback which indicates potential data features, wherein the potential data features are identified from or associated with the data feature and the existing data features and sending, by the feature validation center, the feedback to the feature extraction router to re-extract a new data feature;
- and
- upon determination that the data feature belongs to the feature set, triggering, by the feature validation center, feature-enabled network operations at least in part based on a set of valid data features, the set of valid data features is associated with the feature set.
2 more elements
A device for data feature validation, the device comprising:
- a transceiver module, configured to receive a data feature from a feature extraction router;
- a processing module, configured to determine whether the data feature belongs to a feature set, wherein the feature set includes existing data features provided by a third party off-line, wherein
- upon determination that the data feature does not belong to the feature set, generate, by the processing module, feedback which indicates potential data features, wherein the potential data features are identified from or associated with the data feature and the existing data features and send, by the transceiver module, the feedback to the feature extraction router to re-extract a new data feature;
- and
- upon determination that the data feature belongs to the feature set, trigger, by the processing module, feature-enabled network operations at least in part based on a set of valid data features, the set of valid data features is associated with the feature set and the data feature.
