This study re-examines and contextualises Eduard Seler's investigations in the Chaculá-Region (Department of Huehuetenango, Guatemala). Starting with a discussion of ethnohistory as well as the historical circumstances of Seler's research, his metho

This paper takes a fresh look at security notions for steganography – the art of encoding secret messages into unsuspicious covertexts such that an adversary cannot distinguish the resulting stegotexts from original covertexts. However, stegosystem

In steganography secret messages are encoded into unsuspicious covertexts such that an adversary cannot distinguish the resulting stegotexts from original covertexts. To accomplish their respective tasks, encoder and adversary need information about

This chapter provides an overview, based on current research, on theoretical aspects of digital steganography— a relatively new field of computer science that deals with hiding secret data in unsuspicious cover media. We focus on formal analysis of

We propose a new model of steganography which combines partial knowledge about the type of covertext channel with machine learning techniques to learn the covertext distribution. Stegotexts are constructed by either modifying covertexts or creating n

Recent work on theoretical aspects of steganography resulted in the construction of oracle-based stegosystems. It has been shown that these can be made secure against the steganography equivalents of common cryptographic attacks. In this paper we use
