What is Computer Vision?

Computer vision (CV) is the term given to the technology that allows computers to gain a high level of understanding from digital images or videos.

‍

Evolution of Computer Vision Security

Classical computer vision techniques have existed since the early 1960s, but recent advancements in deep learning algorithms, AI cameras, networks, and computing capabilities have allowed CV to flourish, creating new applications in areas such as computer vision-based access management.

Computer vision holds tremendous potential to solve problems in the healthcare, automotive, and manufacturing industries, to name but a few. 

The widespread adoption of this technology, including its use in security-focused computer vision solutions, is driven by these advancements and the availability of cheaper smart camera infrastructure.

‍

Privacy Concerns in Computer Vision Surveillance

Computer vision-based systems deliver substantial value to organizations and society. Yet, their increased use in surveillance brings new ethical concerns, most notably around privacy.

Many organizations now face increasing pressure to comply with privacy regulations, such as the General Data Protection Regulation (GDPR) for CV, while still benefiting from the technology.

‍

Balancing Privacy and Computer Vision Technology

The concept of privacy acts as a barrier, in many cases, to the deployment of and, thus, to the indisputable benefits that this technology can offer.

The field of privacy in computer vision has recently become a burgeoning research area as more and more organizations are beginning to realize and understand the potential privacy concerns that computer vision could pose.

Worker unions often express concern about how these technologies impact employee privacy, particularly in surveillance-heavy environments.

‍

High-Profile Privacy Breaches and AI Model Vulnerabilities

The understanding of the implications of a privacy breach, as well as the emphasis being put on data privacy, has been driven by recent high-profile examples, which have garnered a significant amount of negative media attention.

Companies are therefore putting a significant emphasis on ensuring that their systems are developed with and underpinned by strong privacy and security research, including the use of facial recognition systems and comprehensive computer vision security platforms for organizations.

There is a particular interplay between security and privacy mechanisms in modern technology systems, with computer vision security providing essential safeguards.

While the security designs embedded in these systems are focused on safeguarding data collection, the privacy principles implemented are focused on safeguarding user identity. There is always a risk of a data breach in any system, which even tech giants have been unable to prevent.

‍

AI-Specific Attacks in Computer Vision Security

AI technologies can also introduce unique vulnerabilities to models. These risks include attack types such as model inversion, which reconstructs training data, and membership inference, where attackers determine if particular data was used. 

Adversarial attacks on computer vision can exploit slight input tweaks to mislead models, and there is also the issue of extracting sensitive information from training data.

‍

Technical Approaches to Visual Data Anonymization

It is, therefore, of the utmost importance that in the event of a data leak, any data leak is encrypted, encoded, or structured in a manner that preserves the privacy and personal data of data stakeholders, often utilizing advanced visual data anonymization methods. 

‍

Image Obfuscation and Re-Identification Risks

Image obfuscation approaches, such as advanced facial blurring and pixelation, must be used thoughtfully, always considering the possibility of re-identification.

‍

Global Perspectives on Data Privacy Regulations

The concept of privacy is difficult to measure and, in some cases, define. Ethical considerations play a significant role in shaping these definitions, which are based on strict individualistic definitions in the Western world. In the East, the definitions are looser and based more upon the collective community.

This is an example of how the very fundamental principles upon which the definition is based can differ drastically.

As such, there are a multitude of gray areas when privacy is discussed in relation to video data, and therefore, it can be difficult to outline a set of concrete rules or guidelines that are compatible with every definition and application.

The frameworks that have been designed and used to inform how this technology should be used are based on guidelines and policies.

‍

Computer Vision Ethics and Societal Impact

In addition to technical and compliance considerations, the use of computer vision systems brings important ethical questions. Addressing issues like algorithmic bias in computer vision, which can result in unfair or discriminatory outcomes, is essential. 

Surveillance ethics must also be evaluated to ensure that data collection and use respect individual rights and public consent. Anticipating and minimizing potential societal risks is a necessary aspect of responsible computer vision deployment.

Privacy by Design Frameworks in Computer Vision

Privacy by Design (PbD) was initially developed and proposed by Ann Cavoukian and formalized by a joint team of data commissioners in 1995.

The Privacy by Design framework was developed in response to the growing amount of information being created in the industrial manufacturing sector and the growing need to manage it responsibly.

Furthermore, Cavoukian referenced increasing system complexity as a factor that presents profound challenges for informational privacy. The framework is based on the active embedding of privacy and centers around 7 principles, described in Fig. 1.

‍

7 Core “Privacy by Design” Principles

Each of these informs system design by presenting high-level objectives to ensure Privacy by Design Principles. They are briefly outlined below:

1. Proactive, not Reactive, Preventative, not Remedial

Privacy risks should be anticipated, and action taken before a privacy infraction occurs. Therefore, PbD is a before-the-fact design measure instead of one that offers remedies to privacy shortcomings.

2. Privacy as the Default Setting

Personal sensitive data should be detected automatically, meaning that the user should not have to enable privacy. In systems such as surveillance and security cameras that rely heavily on computer vision for security and AI-powered monitoring, it should be enabled by default.

3. Privacy Embedded into Design

Privacy should not be treated as an add-on - it should be integral to the system design, particularly in AI models that rely on object detection and biometric data. It should also be an essential component of the core functionality delivered by the system, ensuring the protection of personal information.

4. Full Functionality – Positive-Sum, not Zero-Sum

The implementation of privacy should not result in any unnecessary trade-offs with any other component of the system. It should not hamper the functionality of the system, rendering it useless.

5. End-to-End Security – Full Lifecycle Protection

Strong security systems are essential to ensure all data is securely retained during its life cycle and securely destroyed thereafter.

6. Visibility and Transparency – Keep it Open

All stakeholders of the system and, furthermore, of them should be made aware of the privacy practices or lack thereof that are in place.

7. Respect for user Privacy – Keep it User-Centric

The users of the system are core to any decision being made regarding the privacy of data in any system.

‍

Privacy by Design Examples in Software Development

These principles provide a strong foundation, and a range of privacy by design implementations in software show how they can be put into practice to earn trust and protect individuals. 

This framework came about in an era when the internet and cloud-based systems were beginning to become ubiquitous and central to the way in which large organizations managed their data.

‍

Challenges in Privacy-Preserving Machine Learning

A parallel could be drawn between the early 2000s and now, where recent advancements in Artificial Intelligence and Computer Vision technologies have presented a variety of new challenges with respect to privacy issues and sensitive information, demanding advanced methods such as privacy-preserving machine learning (PPML).

These issues particularly pertain to the complex, convoluted AI-based systems that produce large quantities of data, which can, in some cases, be personally sensitive by nature.

It is this reason why, although the foundational principles of PbD are relevant and still hold importance, they also struggle to implicitly define how these systems should be built and instead exist to inform high-level privacy considerations.

‍

Misconceptions About Privacy Frameworks

This article discusses a common misconception of a privacy framework, particularly PbD, which is that you can simply take a few Privacy-Enhancing Technologies (PETs) and add a good dose of security, thereby creating a fault-proof systems landscape for the future.

Organizational Barriers to Computer Vision Corporate Security Systems

Several challenges arise when implementing privacy by design principles, and these vary based on an organization’s size, maturity, and culture. Difficulties are often driven by the following factors:

Absence of a Privacy-First Culture:

Adopting privacy by design requires a cultural shift in many organizations, prioritizing privacy from the outset rather than treating it as an afterthought. This cultural gap is often compounded by:

• Lack of Key Roles - Without dedicated privacy officers, accountability for privacy controls is weak.
• Short-Term Focus - Prioritizing quick profits over long-term privacy can create conflicting priorities.

Limited Collaboration:

Implementing privacy-preserving techniques requires input from different teams and senior leaders. Without cooperation, efforts to implement it can fail.

Poor Data Management:

Data sprawl and orphaned amounts of visual data complicate identifying privacy challenges, making it challenging to implement effective privacy processes, especially when working with Personally Identifiable Information (PII) found in visual content.

Complying with Global Data Privacy Laws:

Growing privacy laws make compliance tricky, as organizations must follow different rules in each region. Managing these complex data privacy requirements, which may include mandates such as HIPAA for health data or the CCPA for California residents, is a substantial challenge. 

Protecting the rights of data subjects, including access and deletion, adds further complexity.

Fast-Changing Technology:

New technology, such as image recognition and computer vision algorithms, brings both solutions and risks, requiring organizations to stay updated while protecting against emerging privacy violations and threats.
