Hi. Zeena ..I wondered about the same things

Hey,

biometrics is more about planning and statistics.

Bioinformatics is more about developing tools for different biological techniques.

This is a very coarse explanation. Just google biometrics and bioinformatics, you will very soon see the difference.

Regards,

André

Try to depart from the following literature:

"A skin tone detection algorithm for an adaptive approach to steganography"

https://www.sciencedirect.com/science/article/pii/S0165168409001686

and probably you will be interested in the review as well:

https://www.sciencedirect.com/science/article/pii/S0165168409003648

There is a whole bunch of algorithms based on bio-inspired computing, and steganography is not an anomaly. In addition to the literature I have shown you above (where human face and eyes geometry are exploited), fingerprints images are also used. Below, the use of DNA is outlined:

DNA Based Image Steganography

Thank you very much for your good answer and interest in the subject

Bio-metrics refers to two very different fields of study and application. The first, which is the older and is used in biological studies, is the collection, synthesis, analysis and management of data in biology. Bio-metrics in reference to biological sciences, or bio-statistics, has been studied since the early twentieth century.

Bioinformatics is the application of information technology to the field of molecular biology. Bioinformatics entails the creation and advancement of databases, algorithms, computational and statistical techniques, and theory to solve formal and practical problems arising from the management and analysis of biological data.

In bio-metrics, image process is needed for characteristic a private whose bio-metric image is hold on within the information antecedent. Faces, fingerprints, irises, etc., square measure image-based bio-metrics, that need image process and pattern recognition techniques. For a picture based mostly bio-metric system to figure accurately, it must have the sample image of user’s bio-metric very clear and non-adulterated kind.
