Surveillance Data Retention Across Dual Policy Storage Tiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance systems face high costs and challenges in archiving data for extended periods while complying with data retention regulations, particularly in jurisdictions that restrict data storage beyond a predetermined duration.
Innovation Solution
Implement a method and system for data retention that involves moving media stream data from a first retention system with a first retention policy to a second retention system with a different policy, allowing for differentiated storage durations and security protocols based on the level of interest in the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If surveillance data is archived for extended periods to meet investigation or compliance purposes, then data retention capability is improved, but storage costs significantly increase
Solution Approach 1:
The patent segments the archival storage into two distinct systems: a first retention system for short-term storage (e.g., 30-90 days) and a second retention system for long-term storage (e.g., 1-5 years or indefinitely). This segmentation allows the organization to meet compliance requirements for extended retention periods while avoiding the prohibitive costs of storing all surveillance data indefinitely in a single high-cost system.
Solution Approach 2:
The patent applies different storage qualities and policies to different portions of the surveillance data based on their retention requirements. The first retention system uses higher-performance, more accessible storage media suitable for frequent access within the short-term period, while the second retention system uses lower-cost, less accessible storage media appropriate for long-term archival where access frequency is expected to be lower.
2Duration of action of stationary object
If surveillance data is archived for extended periods, then data availability for investigation is improved, but compliance with data retention regulations becomes more difficult
Solution Approach 1:
The patent implements dynamic data movement between the first and second retention systems based on time-based policies. Data automatically transitions from the first retention system to the second retention system after a predetermined time period expires. This dynamic approach allows the system to adapt to varying regulatory requirements across different jurisdictions and automatically adjust storage strategies based on the age and importance of the surveillance data.

AI summary
A method for data retention comprises obtaining, from a first retention system having a first retention policy associated therewith, surveillance data generated by surveillance of a location where a surveillance system is deployed, identifying a level of interest in the surveillance data, and, in response to identifying, based on the level of interest, that at least part of the surveillance data is of interest, causing the at least part of the surveillance data to be stored in a second retention system, the second retention system having associated therewith a second retention policy different from the first retention policy.
