STORAGE DEVICE, HOST SYSTEM HAVING THE SAME AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18199173 titled 'STORAGE DEVICE, HOST SYSTEM HAVING THE SAME AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes an operating method of a storage device that detects fake data by analyzing the similarity of a region of interest (ROI) between decoded data and an adjacent frame.
- Receiving decoded data from a codec
- Determining if the decoded data contains a ROI
- Checking for a first background region in the decoded data that matches a second background region in an adjacent frame
- Calculating the similarity of the ROI between the decoded data and the adjacent frame
- Verifying if the similarity is below a reference value
- Generating detection information if the similarity is below the reference value, indicating fake data
Potential Applications
- Video surveillance systems
- Image processing applications
- Data integrity verification in storage devices
Problems Solved
- Detection of fake or manipulated data
- Ensuring data authenticity and integrity
- Preventing security breaches and fraud
Benefits
- Enhanced data security
- Reliable detection of fake data
- Improved trustworthiness of stored information
Original Abstract Submitted
An operating method of a storage device, includes: receiving decoded data from a codec; determining whether the decoded data includes a region of interest (ROI); based on determining the ROI is included in the decoded data, determining whether the decoded data includes a first background region, other than the ROI, identical to a second background region of an adjacent frame; based on determining the first background region is identical to the second background region, determining a similarity for the ROI between the decoded data and the adjacent frame; determining whether the similarity is lower than a reference value; and based on determining the similarity is lower than the reference value, generating detection information indicating that the decoded data is faked.
