Well it *is* only a guess, but I haven't yet found anything concrete along the lines of "traceological/traseological" etc. in dictionaries or elsewhere which looks likely. There is the French word "tracéologique", which is briefly mentioned in this item about archaeology:

"L'observation typologique des objets, leur expérimentation (fabrication à l'identique) et leur *analyse tracéologique (étude des traces laissées par les outils)* permettent d'expliquer les choix des essences effectuées par les artisans suivant les contraintes techniques imposées par la pièce à façonner."

So if "traseologic" has the same meaning (and I honestly don't know if it does, but it seems reasonably likely), it could also mean simply "trace analysis"... there is also a similar word in Russian ("trassologichesky") which Multitran defines as "trace evidence analysis". Perhaps they are analysing chemical traces on the document (watermarks, ink etc.) to determine whether it is genuine?

The Romanian term seems to relate not only to documents:

"Expertiza traseologica privind identificarea urmelor cauzale si a urmelor ramase pe imbracaminte si pe corpul cadavrelor..."

That sounds very much like trace analysis to me.
