A novel data-nulling superimposed pilot scheme for orthogonal frequency division multiplexing (OFDM) systems is proposed, where the input data vector is spread over all the subcarriers by a precoding matrix and then nulled at certain subcarriers for the insertion of training pilots. This method avo...

Enhancing enterprise security involves implementing various Data Masking techniques such as tokenization, encryption, anonymization, redaction, Format-Preserving Encryption (FPE), substitution, shuffling, noise addition, hashing, nulling, referential masking, partial data exposure, and data swizzling. These ...
Why is data masking important? Data masking solutionsare important to enterprises because they enable them to: Achieve compliance with privacy laws, like CPRA, GDPR and HIPAA, by reducing the risk of exposing personal or sensitive data, as one aspect of the total compliance picture. Protect data...
Nulling out. This is a simple masking strategy where a data field is assigned a null value. This method has limited usage as it tends to fail the application’s logic. Substitution. Original data is substituted by fake, but realistic values. Meaning that the new value still needs to satisfy...
Nulling out: Nulling out replaces data with null values. This technique, while simple, ensures no sensitive information is exposed. However, it’s not always practical in scenarios where the presence of data is needed for operational purposes. Redaction: This technique involves removing sensitive da...
The location and stability conditions of the poles and zeros, boundary conditions of subharmonic instability, and nulling of the audio-susceptibility are also derived. It is proved that the stable operating range of the source voltage is linearly proportional to the ramp slope. The sampled-data ...
Nulling Out or Deletion Ths type of data masking changes data characteristics and takes out any usefulness in data. Variance The data is changed based on the ranges defined. It can be useful in certain situations, e.g., where transactional data that is non-sensitive needs to be protected for...
According to (6-14) type, results in the bipolarity nulling operation code power spectrum function graph as shown in Figure 6-19.Thus it may be known, looked from the bipolarity nulling operation code power spectrum result that, does not contain the direct component, but non-element synchronize...
Nulling – Sensitive data will be replaced with Null values. Encryption – encryption of sensitive information, Redaction – partially masking the sensitive data where only one part of the data is visible. Whereas Dynamic Data Masking involves Full masking, partial masking – Mask portion, random ma...
