Summary
Self-Sovereign Identity (SSI) empowers users by giving them control over their personal data, enhancing privacy by reducing reliance on intermediaries. This systematic review maps SSI
Area of Science:
- Computer Science
- Information Science
- Cybersecurity
Background:
- Self-Sovereign Identity (SSI) is a user-centric model where individuals control their digital identity and data.
- SSI enhances privacy by enabling direct data sharing between users and service providers, bypassing third-party intermediaries.
- The growing interest in SSI has led to a significant increase in related scientific and non-scientific literature.
Purpose of the Study:
- To conduct a comprehensive systematic review and mapping of theoretical and practical advancements in Self-Sovereign Identity (SSI).
- To address key research questions regarding the current state and future directions of SSI.
- To develop a novel taxonomy for categorizing and analyzing SSI publications.
Main Methods:
- Systematic literature review and mapping of academic and technical publications on SSI.
- Analysis of evidence from reviewed materials to answer predefined research questions.
- Development of a new taxonomy to classify and organize SSI literature.
Main Results:
- Identification and analysis of key theoretical and practical contributions to SSI.
- A novel taxonomy was created to categorize and review SSI publications.
- Discussion of current open challenges and future research directions in SSI.
Conclusions:
- SSI represents a significant shift towards user-centric data control and enhanced privacy.
- The systematic review provides a structured overview of the SSI landscape, identifying research gaps.
- Recommendations for future work are proposed to advance the field of Self-Sovereign Identity.

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.

02:57The Sense of Self: Reflected Self-Appraisal and Social Comparison
50.9K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Sigmund Freud's model of the human psyche is often illustrated using an iceberg analogy. The iceberg's visible tip represents the conscious mind, which includes thoughts and perceptions that individuals are immediately aware of. However, the larger, submerged portion of the iceberg represents the unconscious mind, a reservoir of repressed desires, instincts, and memories. According to Freud, human behavior is primarily shaped by this hidden realm.

27.0K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

01:26Marcia's Theory of Identity Status

James Marcia's identity status model provides a framework for understanding how adolescents navigate identity formation through varying degrees of exploration and commitment. Marcia's model builds on Erik Erikson's theories of psychosocial development, focusing specifically on how adolescents reconcile individual aspirations with societal expectations. His model describes identity formation as a dynamic process where adolescents move between different states depending on their level...
