Image Capture Device Proximity-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of creating an access list for digital images is labor-intensive and inefficient, especially in situations with a large number of people who want to access the images, such as weddings or public events.
Innovation Solution
An image capture device sends a wireless invitation signal, receives response signals from nearby devices with unique identifiers, and generates an access list to control access to the images based on the received identifiers, allowing only associated users to access the images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input method is used to create access list, then access control can be implemented, but the process becomes labor-intensive and inefficient for large groups
Solution Approach 1:
The system enables automatic access list generation where the camera device autonomously creates the access list by receiving wireless signals from devices of people present at the event, eliminating the need for manual input while efficiently handling large groups
Solution Approach 2:
The system performs preliminary actions by pre-configuring the camera to automatically generate access lists based on wireless signals received at the time of image capture, so that when images are taken, the access control mechanism is already in place and operational
2Productivity
If automatic access control based on device proximity is implemented, then access control efficiency is improved, but device complexity increases
Solution Approach 1:
The camera device integrates multiple functions including image capture, wireless signal reception, automatic access list generation, and access control enforcement into a single device, which while increasing complexity internally, provides universal functionality that simplifies the overall system architecture
Solution Approach 2:
The system uses wireless signals as an intermediary mechanism to automatically identify and authenticate devices, transferring the complex access control logic from manual processing to automated signal-based identification, thereby improving efficiency while managing complexity through abstraction

AI summary
Embodiments of the invention provide techniques for controlling access to digital images based physical and temporal proximity to the image capture event. In one embodiment, an imaging device capturing a digital image broadcasts an invitation to wireless devices in the surrounding area. The wireless devices respond with an acceptance, including the email address (or some other network address) of the device owner. The digital image is made available at a network location with restricted access. Access to the image is controlled with an access list based on the acceptances received by the imaging device.
