Advantage of Quantified Self

Self-tracking has several benefits such as:

Enhanced self-awareness: People can better understand their routines, preferences, and actions by collecting data on different aspects of their lives.

Improved decision-making: Data-driven insights may help influence choices about personal finances, productivity, and health.

Better motivation: Monitoring one's progress toward objectives can increase motivation and a sense of achievement.

Disadvantage of Quantified Self

However, there are some negative aspects of self-quantification:

Data saturation: Collecting and analyzing a large amount of data may be very challenging and time-consuming.

Obsessive behavior: Too much attention on tracking may lead to the development of an unhealthy addiction with numbers and statistics.

Privacy issues: The collection and storage of personal data are at the center of security and privacy issues that cannot be neglected.

Biometric identification has become the most popular way of confirming identity in various fields, such as airport security and unlocking phones. Biometrics that are based on physical features such as voice, fingerprints, or facial recognition are a more efficient and secure option than traditional methods, such as PINs and passwords.

The cost of stolen data such as biometric data can be very high. As it can be and is used for identity theft and fraud and other criminal activity. If someone with malicious intent gain access to a database containing biometric data of large group of people, they can be uses to impersonate and gain unauthorized access to financial resources and secure locations.

Companies frequently assert that their security procedures are robust, yet a number of incidents demonstrate that inadequate security measures have led to the exposure of private biometric information.  People become more skeptical about the security of their biometric information when they are not given clear information about how their data is handled.

Facial recognition technology has generated controversy, because it might allow for widespread surveillance without people's awareness or agreement. The use of face recognition by governments to follow demonstrators has stifled free speech and assembly in several nations.

Furthermore, there are worries that governments or businesses can gather biometric information about people under the pretense of security and then use it to follow them around to gain more insight for consumer engagement data.

Security of the Biometric data

Organizations can take the following steps to safeguard privacy while collecting biometric data: 

• Encrypt Biometric Information: Organizations should encrypt biometric information when it's being used as well as when it's at rest.  Encryption guarantees that without the right decryption keys, the data will remain unreadable even if it is intercepted or compromised.  This minimizes the possibility of illegal access to private biometric data.

• Create prominent Data Management Policies: It's critical to have transparent and readily apparent data management policies.  Users must be informed by organizations regarding the collection, storage, and sharing of their biometric data.  This transparency promotes confidence and ensures that consumers are aware of the security protocols in place to safeguard their data.

• Local processing: Local processing can be used. Biometrics should be processed locally on the user's device for enhanced privacy. This approach prevents Biometric data from being transmitted directly to the centralized system and to other server sites, which can increase the risk of getting information into the wrong hands.

• Decentralized technologies should be used. Inefficiencies ensure that the data is not kept in a central location, which reduces the chance of large-scale hacks and enhances user privacy. Decentralization provides more effective control over the use of data and its accessibility.

• Organizations should avoid long-term storage of data. The data should be discarded once it has been used for verification.

• Regular audits: Organizations should conduct regular security audits and assessments to identify vulnerabilities in their systems. Compliance with privacy regulations can be ensured with routine audits. The organization's practices align with current privacy standards, as a result of periodic reviews of their data retention policies.

It is important for organizations to balance the need for security and convenience with the responsibility of protecting users' privacy. Businesses can mitigate risks while protecting personal data by learning from past data breeches.
With regulators far behind the times and slow to adopt new policies, technology is quickly outpacing politics. Information is power. Giving personal, biological data to Global companies which are focused on profit and expecting them to handle it in a way that’s beneficial to their customers is a very big (and perhaps naive) gamble.
