  • MobiShare : cloud-enabled opportunistic content sharing among mobile peers 
    Yadav, Kuldeep; Naik, Vinayak; Singh, Amarjeet (2012-10-12)
    In developing countries, smartphones and high bandwidth connections are not yet within the reach of majority of the people. To share multimedia content among themselves, people rely on manual local sharing mechanisms i.e. ...
  • Biclique cryptanalysis of full round AES with reduced data complexity 
    Chang, Donghoon; Ghosh, Mohona; Sanadhya, Somitra Kumar (2013-05-31)
    Biclique cryptanalysis was proposed by Bogdanov et al. in Asiacrypt 2011 as a new tool for cryptanalysis of block ciphers. A major hurdle in carrying out biclique cryptanalysis is that it has a very high query complexity ...
  • Characterizing mobility patterns of people in developing countries using their mobile phone data 
    Yadav, Kuldeep; Kumar, Amit; Bharti, Aparna; Naik, Vinayak (2013-10-10)
    Location data collected from mobile phone users provide an ideal platform to generate human mobility patterns. These patterns give us insights into how people travel in their dayto- day lives.With availability of cellular ...
  • Android phone based appraisal of app behavior on cell networks 
    Gupta, Shaifali; Garg, Rashi; Jain, Nikita; Naik, Vinayak; Kaul, Sanjit Krishnan (2013-10-31)
    The rapid adoption of smartphones has engendered a large ecosystem of mobile data applications. In fact, a large part of mobile tra c is now data and not voice. Many of these applications, for example VoIP clients, stay ...
  • Automated testing of interactive voice response applications 
    Asthana, Siddhartha; Singh, Pushpendra (2014-04-28)
    Dialing a telephone number of an organization and coming across an automated system attending the call, instead of a human, has become common. These automated applications are known as Interactive Voice Response (IVR) ...
  • Face anti-spoofing via motion magnification and multifeature videolet aggregation 
    Bharadwaj, Samarth; Dhamecha, Tejas I; Vatsa, Mayank; Singh, Richa (2014-06-03)
    For robust face biometrics, a reliable anti-spoofing approach has become an essential pre-requisite against attacks. While spoofing attacks are possible with any biometric modality, face spoofing attacks are relatively ...
  • Consumer privacy and targeted pricing with stochastic valuations 
    Mishra, Shreemoy (2014-07-16)
    I study the market for consumer information. Firms cannot commit to privacy, so buyers anticipate disclosure of purchase history for targeted pricing. In the literature, strategic rejections of informative o ers make ...
  • ACCORD : an analytical cache contention model using reuse distances for modern multiprocessors 
    Hemani, Rakhi; Banerjee, Subhasis; Guha, Apala (2014-09-15)
    Simultaneous execution of multiple threads on multicores is necessary for good resource utilization. However, such utilization calls for accurate models to predict the impact on performance due to contention of shared ...
  • An smartphone-based algorithm to measure and model quantity of sleep 
    Gautam, Alvika; Naik, Vinayak; Gupta, Archie; Sharma, SK (2014-09-17)
    Sleep quantity affects an individual’s personal health. The gold standard of measuring sleep and diagnosing sleep disorders is Polysomnography (PSG). Although PSG is accurate, it is expensive and it lacks portability. ...
  • Perception of data privacy in digital forensic investigation 
    Verma, Robin; Gupta, Gaurav (2014-12-25)
    The use of digital technology in conventional as well as new age crimes is increasing throughout the world, and researchers are working to develop digital forensics techniques to investigate such crimes. Digital forensic ...
  • Towards practical infrastructure for decoy routing 
    Chakravarty, Sambuddho; Naik, Vinayak; Acharya, Hrishikesh Bhatt; Tanwar, Chaitanya Singh (2015-01-23)
    Network censorship and surveillance generally involves ISPs working under the orders of repressive regimes, monitoring (and sometimes filtering) users’ traffic, often using powerful networking devices, e.g. routers ...
  • Covariates of face recognition 
    Bhatt, Himanshu S; Singh, Richa; Vatsa, Mayank (2015-01-27)
    Face recognition has found several applications ranging from cross border security, surveillance, access control, multimedia to forensics. Face recognition under variations due to pose, illumination, and expression has ...
  • Biometric quality : from assessment to multibiometrics 
    Bharadwaj, Samarth; Vatsa, Mayank; Singh, Richa (2015-01-27)
    Quality is an attribute or a property of an item that quantitatively measures specific aspect or content. The definition and correct method of measurement of quality of a biometric modality that is usually represented by ...
  • Latent fingerprint matching 
    Sankaran, Anush; Vatsa, Mayank; Singh, Richa (2015-01-27)
    Latent fingerprint comparison evidences are used in the court of law for more than 100 years. Manual matching of latent fingerprints is challenged by subjectivity and inconsistency in terms of results and is not scalable ...
  • UP-Hist Tree : efficient data structure for high utility pattern mining from transaction databases 
    Goyal, Vikram; Dawar, Siddharth (2015-02-11)
    High-utility itemset mining is an emerging research area in the field of Data Mining. Several algorithms were proposed to find high- utility itemsets from transaction databases and use a data structure called UP-tree ...
  • Biclique cryptanalysis of full round AES-128 based hashing modes 
    Chang, Donghoon; Ghosh, Mohona; Sanadhya, Somitra Kumar (2015-03-23)
    In this work, we revisit the security analysis of AES-128 instantiated hash modes. We use biclique cryptanalysis technique as our basis for the attack. The traditional biclique approach used for key recovery in AES (and ...
  • Inference-based LLC-side access pattern estimation for shared cache modeling on commercial processors 
    Hemani, Rakhi; Banerjee, Subhasis; Guha, Apala (2015-05-19)
    Cache contention modeling is necessary for good resource utilization on commercial multicore processors. Our goal is to build cache contention models that are sensitive to changes in, 1) the micro-architecture, 2) ...
  • Analyzing mutable checkpointing via invariants 
    Aggarwal, Deepanker; Kiehn, Astrid (2015-09-10)
    The well-known coordinated snapshot algorithm of mutable checkpointing [7{9] is studied. We equip it with a concise formal model and analyze its operational behavior via an invariant characterizing the snapshot computation. ...
