Electronic Business Card Identifier Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods fail to effectively prevent the leakage and misuse of electronic business cards, leading to harassment and fraud, as stolen cards can still be used to communicate with the original user's terminal.
Innovation Solution
A communication method where only an identifier is displayed for the user account on an electronic business card, requiring authorization through a server to obtain the actual account information for communication, preventing direct communication with the user's terminal even if the card is stolen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic business card is encrypted and only authorized users can decrypt it, then information security is improved, but the decrypted card can still be leaked through screen capture or photographing
Solution Approach 1:
The patent extracts the account information from the electronic business card and replaces it with an identifier. When communication is needed, the system retrieves the actual account information through server authorization based on the identifier, rather than storing or displaying the account information directly on the business card.
Solution Approach 2:
The patent introduces a server as an intermediary between the identifier and the actual account information. The server mediates the authorization process, verifying permissions before revealing the account information, thus preventing direct exposure even if the business card is compromised.
2Reliability
If the account information is hidden on the electronic business card, then privacy protection is improved, but communication functionality cannot be established without revealing the account information
Solution Approach 1:
The patent performs preliminary authorization verification through the server before establishing communication. The system pre-establishes the permission relationship between the identifier and the account information, so that when communication is needed, the authorization has already been validated and the account information can be safely retrieved.
Solution Approach 2:
The patent replaces the direct mechanical link between the business card and account information with a server-based authorization system. Instead of directly exposing account information or using complex encryption/decryption mechanisms, the system uses identifier-based authorization through the server to establish communication.
3Productivity
If the electronic business card is shared widely, then information flowability is improved, but the possibility of information leakage increases
Solution Approach 1:
The patent extracts the account information from the electronic business card and replaces it with an identifier. This allows the business card to be freely shared without exposing sensitive account information, as the identifier alone cannot be used to directly access or communicate with the user.
Solution Approach 2:
The patent introduces a server as an intermediary that controls access to account information. Even when the business card is widely shared, the server mediates all access requests, verifying authorization before allowing communication, thus preventing information leakage while maintaining flowability.

AI summary
Embodiments of this application relate to the field of communications technologies, and provide a communication method and a device, to reduce possibility that account information of a contact corresponding to an electronic business card is leaked. A specific solution includes: receiving, by a first terminal, a first electronic business card sent by a second terminal, where the first electronic business card is an electronic business card of a user corresponding to a client of a third terminal or a client of the second terminal; and displaying, based on the first electronic business card, a first identifier used to identify an account (that is, the first user account) of a user corresponding to the first electronic business card, but skipping displaying the first user account, where the first user account is the account of the user corresponding to the first electronic business card, where the first terminal cannot directly communicate, based on the first identifier, with a terminal of the user corresponding to the first user account, and instead, needs to obtain the first user account based on the first identifier, to communicate with the terminal of the user corresponding to the first user account.
