Embodiment Construction

[0072] Below in conjunction with accompanying drawing, technical scheme of the present invention will be further described:

[0073] The present invention proposes an image acquisition method that takes into account both privacy protection and data quality, comprising the following steps:

[0074] Step 1. Obtain multiple original images according to the image collection task. The image collection task includes multiple subtasks, each subtask corresponds to a type of image collection task, and each subtask includes image collection type, collection quantity, collection area and collection period, etc. The image collection type refers to specific people and things, such as Cats, dogs, children, etc. The method of obtaining the original image is: the cloud issues an image collection task according to the demand, and the image provider (person or collection program, etc.) can accept one or more subtasks, and collect the original image according to the subtasks.

Abstract

The invention discloses an image acquisition method and device considering privacy protection and data quality, and a storage medium, and aims to solve the technical problem that the image privacy protection effect and the data quality are difficult to consider at the same time. The method comprises the following steps: acquiring a plurality of original images according to an image collection task; carrying out differential privacy protection and encoding on the original images to obtain noise-added images and hash codes of the noise-added images; carrying out iterative clustering on the hashcodes of all the noise-added images to form N clusters, and each cluster comprises the hash codes; performing hash code screening according to the Hamming distance between each hash code in a clusterand the centroid point of the cluster to obtain high-quality hash code; and extracting a high-quality image from all the noise-added images according to the high-quality hash code, and taking the high-quality image as a final image acquisition result. Image privacy protection and data quality can be well considered, and the images not prone to privacy leakage, high in availability, high in qualityand high in reliability is obtained.

Description

technical field [0001] The invention relates to an image collection method, device and storage medium that take into account both privacy protection and data quality, and belongs to the technical field of data collection. Background technique [0002] Images have now become an important source of information for enterprises and scientific researchers, especially image datasets with large quantities, high availability, and reliable quality. By mining and analyzing the obtained image data sets, image collectors or users can provide more personalized services for enterprises and provide richer data support for researchers. However, digital images usually contain a wealth of private information. If these images are released directly, the sensitive information in them will be leaked, which will become a way for attackers to benefit. It can accurately locate the user's location; the personal image posted by the user on the network will be modified by the attacker to use it as fra...
