Hierarchical Temporal Memory Consumable Access Control

Review your understanding of the Hierarchical Temporal Memory (HTM) Consumable Access Control System.

Key Concepts

Restricted Resource: A valuable computing resource that requires an access control mechanism, such as storage, network bandwidth, or a specific software service.

Resource Consumer: A user or entity that attempts to access and use a restricted resource.

Training Period: During this period, the system records the usage of restricted resources by authorized users to establish a baseline of usage patterns.

Training Consumer: An authorized user who accesses and uses restricted resources in an approved manner during the training period.

Usage Monitoring: The process of collecting data about how resource consumers use restricted resources during the training and operational periods.

Sparse Distributed Representation (SDR): A data representation method that encodes data as large binary vectors with a small number of active bits.

The bits in these vectors have semantics, and the meaning is distributed across multiple bits, allowing HTM to learn and recognize patterns efficiently.

Hierarchical Temporal Memory (HTM): A machine learning model based on principles of the human brain's neocortex.

It excels at learning and predicting time series data.

In this application, the HTM is trained to recognize authorized resource usage patterns.

HTM Trainer: Component responsible for training the HTM using data from the training period.

HTM Executor: Receives real-time data from the operational period and uses the trained HTM to determine if the current usage pattern matches the learned authorization pattern.

Operational Period: During this period, the system monitors the behavior of resource consumers and uses the trained HTM to determine if their access is authorized.

Anomaly: Any usage pattern that does not match the authorized usage pattern identified by the trained HTM, indicating potential unauthorized access.

Cryptocurrency: A digital asset used as a fault-tolerance mechanism for blockchain-based consumable access control systems.

Blockchain Database: A distributed and secure transaction record that records cryptocurrency allocations and expenditures.

Miner: A network node responsible for validating blockchain transactions and adding them to the blockchain.

Consumable Access Control: An access control mechanism where a user is allocated a certain amount of cryptocurrency that is consumed if a deviation from their learned usage pattern is detected.

Answer

A constrained resource is any valuable computing resource that requires an access control mechanism to manage its usage. Examples include storage systems, network bandwidth, or specific software services.

HTMs are trained to learn authorized resource usage patterns and act as an anomaly detection system during operational time periods, flagging deviations from the learned patterns.

SDRs provide an effective and efficient way to represent data by encoding it as large binary vectors with a small number of active bits, enabling HTMs to effectively learn and recognize patterns.

The training period is used to train the HTM about authorized usage patterns using the activities of the training consumers, while the operational period involves using the trained HTM to monitor and evaluate access requests from resource consumers.

The training consumers access restricted resources in an approved manner during the training period, providing the HTM with the necessary data for learning authorized usage patterns.

Usage monitoring collects data about the behavior of resource consumers, providing the HTM with information for analyzing and identifying potential anomalies during the training and operational periods.

In the context of consumable access control, an anomaly is any activity that does not match the established authorized usage patterns identified by the trained HTM, which indicates a possible policy violation or unauthorized access.

Cryptocurrency is used as a fault tolerance mechanism to allow users to deviate from established usage patterns within certain limits. If an anomaly is detected, the cryptocurrency allocated to the user is consumed, and if it exceeds a predefined threshold, further access is blocked.

The blockchain database provides a secure and tamper-proof transaction record of cryptocurrency allocations to users and any subsequent expenditures due to detected anomalies.

Miners are responsible for validating transactions within the blockchain network. They ensure the integrity of transactions and add them to the blockchain, maintaining the foundation of trust and transparency within the system.
