## Summary
Kleptography is the study of stealing information securely and subliminally. It is classified as a distinct field of study and operates as a specialized subclass of cryptography, which generally focuses on the practice and study of secure communication techniques.

## Key Facts
*   **Definition:** Kleptography is defined as the study of stealing information securely and subliminally.
*   **Parent Classification:** It is a subclass of **cryptography**, the practice and study of techniques for secure communication.
*   **Entity Type:** It is recognized academically as a **field of study**.
*   **Wikipedia Presence:** The entity has a dedicated Wikipedia title ("Kleptography") and is documented across 8 language editions (including English, German, Russian, and Japanese).
*   **Knowledge Base IDs:** The topic is indexed under the Freebase ID `/m/05lgyd` and has a Microsoft Academic ID of 137856018 (discontinued).
*   **Categorization:** Its main topic category is designated as "Category:Kleptography."

## FAQs
### Q: What is the primary focus of kleptography?
A: The primary focus of kleptography is the study of methods to steal information in a manner that is both secure and subliminal, meaning the theft is hidden within cryptographic processes.

### Q: How is kleptography related to cryptography?
A: Kleptography is a subclass of cryptography. While cryptography broadly covers secure communication techniques, kleptography specifically narrows its focus to the exploitation and subversion of these techniques for information theft.

### Q: Is kleptography a widely recognized academic field?
A: Yes, it is classified as a field of study with structured data in major knowledge bases like Wikidata and Wikipedia, where it is linked to the broader discipline of cryptography.

## Why It Matters
Kleptography matters because it addresses the specific vulnerabilities inherent in cryptographic systems when they are used maliciously. While traditional cryptography is concerned with building defenses to protect data, kleptography is the study of how those very defenses can be weaponized to leak data covertly.

This field is significant in the realms of cybersecurity and intelligence because it explores "subliminal" channels—methods of exfiltration that are difficult to detect because they mimic normal, secure traffic. By defining the mechanisms of stealing information "securely," kleptography provides a framework for understanding how cryptosystems can be backdoored or compromised without alerting the user. It serves as a critical area of study for security professionals attempting to verify the integrity of "secure" communication tools.

## Notable For
*   **Unique Niche:** It is a specialized subclass of cryptography that focuses exclusively on the theft of information rather than just its protection.
*   **Stealth Focus:** It is distinguished by its emphasis on "subliminal" theft, prioritizing covertness alongside security.
*   **Structured Classification:** It is a distinct "field of study" with dedicated categorization in major encyclopedic and academic databases.
*   **Global Documentation:** The concept is established enough to possess Wikipedia entries in 8 different languages.

## Body
### Definition and Scope
Kleptography is the study of stealing information securely and subliminally. It represents a intersection of cryptanalysis and steganography, focusing on how an attacker can leak information from a cryptosystem in a way that is computationally infeasible to detect.

### Classification and Hierarchy
The field is strictly defined within knowledge bases as an **instance of** a "field of study" and a **subclass of** **cryptography**.
*   **Cryptography (Parent Class):** Defined as the practice and study of secure communication techniques.
*   **Relationship:** Kleptography inherits the principles of cryptography but applies them to the reverse goal of information extraction.

### Data and Identifiers
The entity is tracked across several semantic web and academic databases:
*   **Wikidata:** Described as the "study of stealing information securely and subliminally."
*   **Wikipedia:** Maintains a presence across 8 linguistic sites (cs, de, en, it, ja, ko, lmo, ru) with a total sitelink count of 8.
*   **Legacy IDs:** Includes a Microsoft Academic ID (137856018) and a Freebase ID (`/m/05lgyd`).
*   **Quora Topic:** Indexed as a topic under the label "Kleptography."
