  1. 1. Digital innovation management : investigating digital trace data in online communities

    Författare :Vasili Mankevich; Jonny Holmström; Ola Henfridsson; Jan Recker; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital innovation; digital trace data; online communities; computational methods; recombination; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : Firms and individuals are interacting online on an unprecedented scale. These interactions may lead to new digital products, services and practices, all of which are manifestations of digital innovation. This process relies on records users leave on various digital platforms which carry information about their activities – digital trace data. LÄS MER

  3. 2. Some aspects of cryptographic protocols : with applications in electronic voting and digital watermarking

    Författare :Björn Terelius; Douglas Wikström; Helger Lipmaa; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cryptographic protocols are widely used on the internet, from relatively simple tasks such as key-agreement and authentication to much more complex problems like digital cash and electronic voting. Electronic voting in particular is a problem we investigate in this thesis. LÄS MER

  4. 3. Traceable Information Systems : Factors That Improve Traceability Between Information and Processes Over Time

    Författare :Lena-Maria Öberg; Viveca Asproth; Per Flensburg; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Traceability; Preservation of Information; Processes; Context; Synergy-4; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Preservation of information is not a new issue but preservation of digital information has a relatively short history. Since the 60’s when computers began to be used within administration, digital information that has had to be preserved over time.The problem addressed in this research is how to preserve understandable information over time.

  5. 4. Towards Trustworthy and Secure Internet of Things Devices : Using hardware-assisted Trusted Execution and Automated Certification

    Författare :Anum Khurshid; Shahid Raza; Thiemo Voigt; Christian Gehrmann; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Internet of Things; IoT device security; Trusted Execution Environments; Trusted Platform Module; TPM 2.0; IoT Certification; Assurance; TrustZone-M; TEE; Secure software updates; X.509;

    Sammanfattning : The advent of Trusted Execution Environments (TEEs) for IoT aligns with the reinforcement of IoT security through recent laws and regulations. A major part of IoT systems comprises of resource-constrained devices, with less margin in memory and computation capabilities to embed sophisticated security solutions. LÄS MER

  7. 5. Contracts and Computation — Formal modelling and analysis for normative natural language

    Författare :John J. Camilleri; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; normative texts; contract analysis; controlled natural language; model checking;

    Sammanfattning : Whether we are aware of it or not, our digital lives are governed by contracts of various kinds, such as privacy policies, software licenses, service agreements, and regulations. At their essence, normative documents like these dictate the permissions, obligations, and prohibitions of two or more parties entering into an agreement, including the penalties which must be paid when someone breaks the rules.
