Dynamic Identity Profiles for Mobile Device Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication networks face challenges in protecting user identity due to the persistent nature of identifiers like IMSI and IMEI, making users susceptible to location tracking and privacy breaches, especially in active signal interception and network operator equipment access threats.
Innovation Solution
A mobile device and server system that manage multiple identity profiles, allowing the device to automatically switch between them frequently, transmitting authentication information to different networks, and optimizing profile usage to prevent location tracking and identity correlation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single persistent identifier (IMSI/IMEI) is used for authentication, then network authentication and accounting are enabled, but user location tracking and identity correlation become easier
Solution Approach 1:
The patent implements dynamic identity selection by switching between multiple IMSI/IMEI profiles stored in the device. Instead of using a single persistent identifier, the system dynamically selects different identities based on operational context, time, and network conditions. This dynamic approach breaks the correlation between device and user identity over time, preventing tracking while maintaining reliable authentication.
Solution Approach 2:
The patent creates multiple copies of identity profiles (IMSI/IMEI combinations) stored in the mobile device. Each profile acts as a valid copy that can be used for authentication. By having multiple identity copies available, the system can rotate between them to prevent tracking, while each individual copy maintains full authentication capability with the network.
2Adaptability or versatility
If multiple SIM cards are used to reduce tracking, then cost separation (work/personal) is enabled, but the device identifier (IMEI) remains persistent and trackable
Solution Approach 1:
The patent segments the identity function into multiple independent profiles, each containing both IMSI and IMEI information. Instead of relying on multiple SIM cards while keeping one persistent device ID, the system creates segmented identity packages where each profile is a complete, independent authentication set. This segmentation allows the device to present different identity combinations to the network, breaking the persistent device identification link.
Solution Approach 2:
The patent makes the mobile device universally capable of using multiple identity profiles for different purposes (work, personal, temporary, etc.). The device can function with any of the stored profiles, making it multi-functional in terms of identity presentation. This universality replaces the need for multiple physical SIM cards while adding the capability to dynamically switch identities, preventing tracking.
3Object-affected harmful factors
If identity profiles are frequently switched to protect privacy, then location tracking difficulty increases, but communication overhead and fraud risk increase
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors network responses, authentication success rates, and potential fraud indicators. Based on this feedback, the identity selection algorithm adjusts its behavior - switching profiles more or less frequently, selecting specific profiles for specific networks, and avoiding patterns that might trigger fraud detection. This feedback-driven approach optimizes privacy protection while minimizing communication overhead and fraud risk.
Solution Approach 2:
The patent changes key parameters of identity profiles including IMSI, IMEI, and associated authentication data. By modifying these parameters across multiple profiles and selectively changing them based on operational context, the system achieves frequent identity switching for privacy protection. The parameter changes are managed efficiently by storing multiple pre-configured profiles with varied parameters, reducing the complexity of real-time generation.

AI summary
A mobile device (1) is configured to receive a plurality of identity profiles from a server system (11), store the plurality of identity profiles in a storage means (7), select a first identity profile from the plurality of identity profiles, and transmit authentication information to a mobile communication network (21,22,25) in order to use the mobile communication network. The authentication information comprises an identifier from the first identity profile. The mobile device is further configured to detect an identity change event, select a second identity profile from the plurality of identity profiles upon detecting the identity change event, and transmit further authentication information to the mobile communication network or to a further mobile communication network (23,26). The further authentication information comprises an identifier from the second identity profile.
