Augmented Reality Controlled Information Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and methods to securely encrypt sensitive information for viewing by augmented reality devices, particularly in environments where trustworthiness of network infrastructure and physical access is compromised, to prevent unauthorized access and data leakage.
Innovation Solution
The method involves automatically identifying controlled information using natural language processing and data loss prevention policies, tokenizing it, and generating public and private keys to encrypt the information, replacing the original text with encrypted markers, and sending these markers to an augmented reality device for secure decryption and display, while using biometric authentication to authorize access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is transmitted via network infrastructure, then information can be accessed and displayed, but the network infrastructure may be insufficiently trustworthy and vulnerable to unauthorized access and interception
Solution Approach 1:
The patent introduces encrypted markers as an intermediary between the information source and the augmented reality device. These markers contain encrypted controlled information that can be transmitted through potentially untrusted network infrastructure. The encryption acts as a mediator that protects the information during transmission, allowing accessible information flow while maintaining security against network vulnerabilities.
Solution Approach 2:
The patent transforms controlled information into a different parameter state through encryption. The original plaintext information is converted into encrypted markers using cryptographic algorithms, changing its representational form. This parameter transformation ensures that even if intercepted during network transmission, the information remains protected and can only be decrypted by authorized devices with the proper keys.
2Ease of operation
If controlled information is displayed on screens or paper in physical environments, then information is accessible to users, but physical environments are insufficiently trustworthy and vulnerable to opportunistic observation and unauthorized copying
Solution Approach 1:
The patent uses encrypted markers as an intermediary representation of controlled information that can be displayed in augmented reality overlays. Instead of displaying plaintext information directly on screens or paper where it would be visible to opportunistic observers, the system displays encrypted markers that appear as ordinary visual elements to unauthorized observers but can be decrypted and read only by authorized augmented reality devices with proper authentication.
Solution Approach 2:
The patent applies different security qualities to different viewing contexts. Authorized users with proper authentication can view and interact with the decrypted controlled information through their augmented reality devices, while unauthorized observers see only the encrypted marker placeholders which appear as meaningless visual elements. This local differentiation of information quality based on authorization status protects against physical observation risks while maintaining usability for authorized users.
3Extent of automation
If screen capture and mobile camera technologies are used to copy information, then authorized users can make unauthorized copies, but this compromises information control and security
Solution Approach 1:
The patent replaces directly viewable controlled information with encrypted markers that serve as intermediaries. When users attempt to capture screenshots or photograph the display, they only capture the encrypted marker placeholders rather than the actual controlled information. The real controlled information exists only in decrypted form within the authorized augmented reality device's memory, protected from external capture attempts.
Solution Approach 2:
The patent creates encrypted copies of controlled information that are distributed to authorized augmented reality devices. These encrypted markers can be safely copied and transmitted through network infrastructure or physical media without compromising security, as the copies remain encrypted and useless without the proper decryption keys. This allows controlled information to be replicated and distributed to authorized users while preventing unauthorized copying of the actual sensitive data.
Data Source
AI summary
The disclosed computer-implemented method for selectively encrypting controlled information for viewing by an augmented reality device may include (i) automatically identifying, at a computing device and using at least one of natural language processing and/or a pre-defined data loss prevention policy, a portion of a source text including controlled information, (ii) tokenizing the portion of the source text, and (iii) performing a security action that may include (A) generating a public key, (B) encrypting the tokenized portion of the source text with the public key to produce an encrypted marker, and (C) replacing the portion of the source text with the encrypted marker to produce a replacement document. Various other methods, systems, and computer-readable media are also disclosed.
