Ορολογία της Ημέρας (T.O.D) – 21/2/2017 [Ransomware]

Ransomware is malware for data kidnapping, an exploit in which the attacker encrypts the victim’s data and demands payment for the private decryption key.

Ransomware spreads through email attachments, infected programs and compromised websites. A ransomware malware program may also be called a cryptovirus, cryptotrojan or cryptoworm.

Attackers may use one of several different approaches to extort money from their victims: Continue reading

Ορολογία της Ημέρας (T.O.D) – 19/2/2017 [Knowledge Based Authentication]

Knowledge-based authentication (KBA) is an authentication scheme in which the user is asked to answer at least one “secret” question. KBA is often used as a component in multifactor authentication (MFA) and for self-service password retrieval. Continue reading

Ορολογία της Ημέρας (T.O.D) – 29/1/2017 [Machine Learning]

Machine learning is an area of computer science and statistical modeling that allows a computer program to predict an outcome or make a decision without being explicitly programmed to do so.

Machine learning, which forms the basis for artificial intelligence (AI), is closely tied to data analytics and data mining programming. Continue reading

On bots, language & making tech disappear — TechCrunch (βγαίνουν τα σώψυχα αν μιλάς με botakia?)

This year’s new buzzword in computer design circles is without question “bots.” As with anything we build, we give bots names. A name can be a way of expressing trust in an object — or expressing control over it. But giving a bot an identity isn’t always for the best. Calling a bot Siri does…

Ορολογία της Ημέρας (T.O.D) – 12/1/2017 [Fruit of the poisonous tree]

Fruit of the poisonous tree is a legal doctrine according to which any secondary evidence obtained indirectly through illicit means is inadmissible in court.

Examples of such sources include evidence gained through eavesdropping, illegal wiretapping, coercive interrogations, unwarranted searches or improperly conducted arrests. Information obtained from those sources is inadmissible according to the law of exclusion. The fruit of a poisonous tree doctrine is an extension to that law. Continue reading

Ορολογία της Ημέρας (T.O.D) – 11/01/2016 [Greedy Algorithm]

A greedy algorithm is a mathematical process that looks for simple, easy-to-implement solutions to complex, multi-step problems by deciding which next step will provide the most obvious benefit.

Such algorithms are called greedy because while the optimal solution to each smaller instance will provide an immediate output, the algorithm doesn’t consider the larger problem as a whole. Once a decision has been made, it is never reconsidered. Continue reading

Data Science & Ιατρική – Μάχη με όπλο την Ανάλυση Δεδομένων ενάντια σε ανίατους εχθρούς

The complexity of seeking a cure for cancer has vexed researchers for decades. While they’ve made remarkable progress, they are still waging a battle uphill as cancer remains one of the leading causes of death worldwide. Yet scientists may soon have a critical new ally at their sides — intelligent machines — that can attack…
