Reference excerpt

Markus Jakobsson is a computer security researcher, entrepreneur and writer, whose work is focused on the issue of digital security.

Career Markus Jakobsson is currently chief scientist at Artema Labs, a company with the mission of disrupting and improving the crypto and NFT markets. Prior to his current role, he has been chief scientist at ByteDance; chief of security and data analytics at Amber Solutions, and chief scientist at Agari. Prior to that, he was a senior director at Qualcomm as a result of Qualcomm acquiring FatSkunk in 2014; Jakobsson founded FatSkunk in 2009, and served as its CTO until the acquisition. Prior to his position at Qualcomm, Jakobsson has served as principal scientist of Consumer Security at PayPal, held positions as the principal scientist for Palo Alto Research Center and RSA Security, and served as vice president of the International Financial Cryptography Association. Prior to these positions, he was a member of the technical staff at Bell Labs, and held a position at Xerox PARC. In addition, Jakobsson serves as an expert witness and is a member of the software and networking litigation group Harbor Labs. He has a background in higher education, having served as an associate professor at Indiana University where he was also a cybersecurity researcher and co-director of the Center for Applied Cybersecurity Research. He has also served as an adjunct associate professor at New York University.

Companies founded and advisory positions In, 2021, Jakobsson co-founded Artema Labs. In 2004, Jakobsson was one of the founders of the digital security company RavenWhite. The Silicon Valley company offers device identification technologies and other authentication solutions for businesses that pair customer identity with digital privacy. In 2006, he launched securitycartoon.com with Dr. Sukamol Srikwan. A website using comics to teach security awareness and understanding among the average internet user, it became the basis for the company Extricatus, which developed Fastwords, an online password creation system where users create secure passwords made of a string of everyday words in order to make them easy to remember. In 2009, Jakobsson co-founded Fatskunk, a company that targets malware that attacks wireless devices such as tablets and smartphones. He founded ZapFraud Inc in 2013. ZapFraud is an IP holding company with a portfolio related to targeted email attacks, including phishing and business email compromise. Markus has served on the advisory boards for Metaforic, a VC-backed company that markets software that other developers can incorporate into their own for greater security, and Lifelock, an identity protection company. In addition, he is a visiting research fellow of the Anti-Phishing Working Group (APWG), an organization focused on reducing cybercrime.

Education Jakobsson holds a PhD in computer science from the University of California at San Diego, as well as master's degrees from both the University of California at San Diego and Lund University in Sweden.

Academic research Jakobsson's early research publications were focused on cryptography. Later research emphasis was aimed at understanding and preventing fraud. With Filippo Menczer and two students, he also conducted live experiments on Internet users in order to determine the ways users were likely to fall victim to various forms on online fraud. His later research was focused toward mobile security and the detection of malware on mobile platforms. In a 1999 paper he, together with Ari Juels, coined the term "proof of work", a central concept in cryptocurrencies such as Bitcoin.

Personal life He is the brother of Hampus Jakobsson, an investor and tech entrepreneur, and Andreas Jakobsson, a professor of mathematical statistics at Lund University.

Bibliography Jakobsson is the author or editor of a series of books and studies dealing with the world of internet security and its practical applications for businesses and individual users.

Worked examples

Example 1 — a first encounter with Markus Jakobsson

Start with the simplest possible case. Write down what Markus Jakobsson claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Markus Jakobsson before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Markus Jakobsson ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Markus Jakobsson

In research: Markus Jakobsson appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Markus Jakobsson in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Markus Jakobsson is common in secondary-school and first-year university syllabi. It links to neighbouring topics American male writers, Living people, Lund University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Markus Jakobsson outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
