Undeciphered writing system

An undeciphered writing system is a  written form of language that is currently not understood. In this context, a writing system is used to mean a series of glyphs; these glyphs may represent writing in a language. However, this is not known until they are deciphered. 

Not being able to decipher a text can have several reasons:

 The language may be a language isolate (there are few or no similar languages that still exist)
 There may be very few texts in the given language
 What is considered a text in a language really is not: it may just be decorations, but the symbols have no semantic meaning.

There is also the concept of false writing systems: these are constructed sets of symbols that are meant to represent a writing system, but that do not.
